Answer:
its called Toxoplasmosis.
Explanation:
Cats become infected by Toxoplasma gondii by ingesting the cysts of this parasite. Most often, this occurs when cats eat mice or rats infected with the parasite. However, they can also ingest it during grooming after coming in contact with infected soil or feces.

Jane made this picture to represent a chemical reaction:
Two circles, one white and the other gray are shown on the left. A small portion of the two circles overlap and the label below the circles is XY. An arrow pointing right is shown on the right of the overlapping circles. There are two circles on the right of the arrow, one white and the other gray, and there is a plus sign between them. The white circle is labeled X and the gray circle is labeled Y.
Which of the following statements best explains the type of chemical reaction represented by Jane's picture? (5 points)
It represents a synthesis reaction because one combined reactant forms multiple products.
It represents a synthesis reaction because the same atoms are present in the reactants and products.
It represents a decomposition reaction because one reactant breaks apart and forms two products.
It represents a decomposition reaction because the total mass of the products is less than the mass of the reactant.
The reaction represents a decomposition reaction because XY is broken into its constituents.
A decomposition reaction is one in which the reactant is broken up into its constituents. In this case, the reactant is XY. The reactant is shown in the left hand side. The reactant is broken up to yield the products. X and Y.
Since the reactant was broken up into the one white and one gray circles labelled X and Y, then the reaction is a decomposition reaction.

When the equation for the reaction represented below is balanced and all coefficients are reduced to lowest whole-number terms, the coefficient for Al(s) is __ Al(s) + __ O2(g) __ Al2O3(s)
This question is asking for the correct balanced reaction, when solid aluminum reacts with gaseous oxygen to form solid aluminum oxide, according to the law of conservation of mass, which demands us to have the same number of atoms of each element on both sides of the equation.
In such a way, we can start by knowing there is one aluminum atom on the left and two on the right whereas there are two oxygen atoms on the left and three on the right side of the equation.
The aforementioned means we must balance oxygen first by putting a 2 on aluminum oxide and a 3 on oxygen in order to cross multiply and obtain six oxygen atoms on both sides of the equation.
Moreover, the 2 on the aluminum oxide makes four aluminum atoms on the right, which means we must put a 4 on the left-handed aluminum in order to get the correct balance, and therefore, write the following balanced equation:
4Al(s) + 3O₂(g) ⇒ 2Al₂O₃(s)
Hence, the coefficient for Al, as asked, is 4.

The Haber process can be used to produce ammonia (NH3) from hydrogen gas (H2) and nitrogen gas (N2). The balanced equation for this process is shown below. 3H2 N2 Right arrow. 2NH3 The molar mass of NH3 is 17. 03 g/mol. The molar mass of H2 is 2. 0158 g/mol. In a particular reaction, 0. 575 g of NH3 forms. What is the mass, in grams, of H2 that must have reacted, to the correct number of significant figures? 0. 1 0. 102 0. 10209 0. 1021.
Answer:
B
Explanation:
We are given that ammonia can be produced from hydrogen gas and nitrogen gas according to the equation:
[tex]\displaystyle 3\text{H$_2$} + \text{N$_2$} \longrightarrow 2\text{NH$_3$}[/tex]
We want to determine the mass of hydrogen gas that must have reacted if 0.575 g of NH₃ was produced.
To do so, we can convert from grams of NH₃ to moles of NH₃, moles of NH₃ to moles of H₂, and moles of H₂ to grams of H₂.
We are given that the molar masses of NH₃ and H₂ are 17.03 g/mol and 2.0158 g/mol, respectively.
From the equation, we can see that two moles of NH₃ is produced from every three moles of H₂.
With the initial value, perform dimensional analysis:
[tex]\displaystyle \begin{aligned} 0.575\text{ g NH$_3$}& \cdot \frac{1\text{ mol NH$_3$}}{17.03\text{ g NH$_3$}} \cdot\frac{3\text{ mol H$_2$}}{2\text{ mol NH$_3$}} \cdot \frac{2.0158\text{ g H$_2$}}{1\text{ mol H$_2$}} \\ \\ & = 0.102\text{ g H$_2$}\end{aligned}[/tex]
*Assuming 100% efficiency.
Our final answer should have three significant figures. (The first term has three, the second term has four (the one is exact), the third term is exact, and the fourth term has five. Hence, the product should have only three.)
In conclusion, our answer is B.

can somebody please help me here ? i wanna make sure of my answer..
Answer:
[Unfortunately] Answer is A
Explanation:
You should know that 'liquid' is a state of matter and aqueous means that there is water present.
-It is mentioned that barium chloride is a solution. So you can cut off the C option.
-Barium sulfate is a salt which means it's a solid, so you can cut off the D option.
We now have A and B as the only options remaining.
-Dilute sulfuric acid is definitely not a liquid because water is present. (dilute indicates that there is a greater proportion of water)
The answer should be A.
A sample of a certain gas has a volume of 452 mL at 711 mmHg and 26 degrees C. What would be the volume of this same sample of gas if it were measured at STP
The volume of this same sample of gas if it were measured at STP is 386.09mL
HOW TO CALCULATE VOLUME:
The new volume of a gas sample can be calculated using the following expression:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressureP2 = final pressureV1 = initial volumeV2 = final volumeT1 = initial temperatureT2 = final temperatureAccording to this question, a sample of a certain gas has a volume of 452 mL at 711 mmHg and 26°C (299K).
(711 × 452)/299 = 760 × V2/273
1074.82 = 2.78V2
V2 = 1074.82 ÷ 2.78
V2 = 386.09mL
Therefore, the volume of this same sample of gas if it were measured at STP is 386.09mL.

Answer:
there are 7. 505 x 1022 atoms in 3.5 grams of silicon.
Explanation:
So, 1 mole of silicon will have a mass of 28.0855 g and the number of atoms will be 6.022 x 1023. Therefore, there are 7. 505 x 1022 atoms in 3.5 grams of silicon.
Answer:
1 mole of silicon will have a mass of 28.0855 g and the number of atoms will be 6.022*1023 . Therefore , there are 7.505*1022 atom in 3.5 g of silicon .

The bowl of fruit has a mass of 2.2 kg.
What net force must act on the bowl of fruit to make it accelerate to the right
at a rate of 4.4 m/s2? (Hint: Use F = ma.)
A. F = 9.68 N right
B. F = 9.68 N left
C. F = 6.60 N left
D. F= 6.60 N right
Taking into account the Newton's second law, the correct answer is option A. F = 9.68 N right
In first place, acceleration in a body occurs when a force acts on a body.
Newton's second law states that a force will change the speed of an object because the speed and/or direction will change. These changes in velocity are called acceleration.
So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object
Mathematically, Newton's second law is expressed as:
F= m×a
where:
F = Force [N] m = Mass [kg] a = Acceleration [m/s²]In this case, you know:
F= ? m= 2.2 kg a= 4.4 m/s²Replacing in Newton's second law:
F= 2.2 kg× 4.4 m/s²
Solving:
F= 9.68 N
Finally, As the bowl of fruit accelerates to the right, the correct answer is option A. F = 9.68 N right

which compound contains both ionic and covalent bonds
Answer:
Any compound that contains a metal ion and a polyatomic ion would work. Polyatomic ions are covalently bonded non-metals that have some overall charge. Examples of common polyatomic ions include OH⁻ (hydroxide), NH₄⁺ (ammonium), and NO₃⁻ (nitrate). So answers to this question can be something like KOH (potassium hydroxide), but really, anything works if it contains a metal ion and a polyatomic ion.
