Answer: what would swimming in mathane lake on titan feel like.

Explanation:

Both methane and titan are gases that are combustible in nature.

Those gases which are inflammable are called combustible gases.

For example:-

These gases have various uses in daily life. these uses as follows:-

The gas will mix in the lake which harms the aquatic animals. The aquatic animals have a hard time to breath.

Hence, the lake will be polluted.

Answer:

Reflection takes place from the polished smooth surfaces

Explanation:

A vacuum does not refer to an opaque body. An opaque body does not allow light to pass through it while a vacuum is simply empty space without air.

A smooth polished surface often acts as a mirror, it is a good reflector of light.

The moon is a non luminous body in the sky. It merely reflects the light from the sun.

Answer:

The pair co,Ni is out of order in terms of atomic mass

Explanation:

For co,Ni

Atomic mass of Co = 58.9331 u

Atomic mass of Ni = 58.6934

For Li,be

Atomic mass of Li = 6.941 u

Atomic mass of  be = 9.012182 u

For I,xe

Atomic mass of I =  126.90447 u

Atomic mass of Xe = 131.293 u

Hence, the pair co,Ni is out of order in terms of atomic mass

Answer:

As a substance melts, and goes from a solid to a liquid state, the kinetic energy of the molecules increases, and the molecules move faster, and they separate further and further away from each other.  The intermolecluar forces holding the molecules together become weaker.  This is why a liquid can take fill the shape of its container, whereas a solid has a fixed shape.

Answer:

When 1.20 mole of ammonia reacts, 1.8 moles of water are produced.

Explanation:

The balanced reaction is:

4 NH₃(g) + 5 O₂(g) → 4 NO (g) + 6 H₂O

By stoichiometry of the reaction, the following amounts of moles participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 4 moles of ammonia produce 6 moles of water, 1.2 moles of ammonia will produce how many moles of water?

[tex]moles of water=\frac{1.2 moles of ammonia*6 moles of water}{4 moles of ammonia}[/tex]

moles of water= 1.8 moles

When 1.20 mole of ammonia reacts, 1.8 moles of water are produced.

Answer:

6.46g of PbCl2 are produced

Explanation:

The PbCl2 will not react, is a product of the reaction. The question must be say how many grams of PbCl2 will be produced

Based on the chemical reaction:

Pb(NO3)2(aq)+2KCI(aq) → PbCl2(s)+2KNO2 (aq)

1 mole of PbCl2 is produced when 2 moles of KCl are reacting.

To solve this question we must find the moles of KCl that will react. With these moles we can find the moles of PbCl2 and the grams produced using its molar mass:

Moles KCl:

0.46L * (0.101moles / L) = 0.04646 moles KCl

Moles PbCl2:

0.04646 moles KCl * (1mol PbCl2 / 2mol KCl) =

0.02323 moles of PbCl2 are produced

Mass -Molar mass PbCl2: 278.106g/mol-

0.02323 moles * (278.106g / mol) =

Answer: The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.

Answer:

3.01x10^23

Explanation:

In order to determine the amount of molecules, you have to use Avogadro's number which = 6.02x10^23. To calculate this, multiply the number of moles with Avogadro's number to get the above answer.
