Answer:

101.4pKa

Explanation:

Given parameters:

Initial Volume of helium = 3.20L

Final pressure of helium = 59kPa

Final volume on helium gas = 5.5L

Unknown:

Initial pressure exerted on the balloon = ?

Solution;

To solve this pressure - volume problem, we simply apply the Boyle's law.

It states that "the volume of a fixed mass gas varies inversely as the pressure changes if the temperature is constant".

Mathematically;

P1 V1 = P2 V2

Now, insert parameters and solve;

P1 x 3.2 = 59 x 5.5

P1 = 101.4pKa

4.2g of cerium reacted with oxygen to form 5.16g of an oxide of cerium. Find

olganol [36]

Answer:

CeO₂

Explanation:

Hello!

In this case, since we are given the mass of both cerium and the cerium oxide, we can first compute the moles of cerium and the moles of oxygen as shown below:

$n_{Ce}=4.2gCe*\frac{1molCe}{140.12gCe}=0.03molCe\\$

$m_O=5.16g-4.2g=0.96gO\\\\n_O=0.96g*\frac{1molO}{16.0gO} =0.06molO$

Now, we simply divide each moles by 0.03 as the fewest moles in the formula to obtain the simplest formula (empirical formula) of this oxide:

$Ce=\frac{0.03}{0.03}=1\\\\O =\frac{0.06}{0.03}=2$

Thus, the formula turns out:

$CeO_2$

Solids have: fixed shape O A and B fixed size neither A nor B

Lemur [1.5K]

Answer:

B. A and B

Explanation:

1. Solids have a definite volume, definite size and definite shape

2. The particles present in a solid are very closely packed since the intermolecular forces between them are very strong. The molecules do not move apart.

3. Melting point is the temperature at which solid changes into a liquid.

4. When a solid is heated to the melting point the intermolecular forces are overcome by the energy and the molecules present in it moves from its fixed position to take its liquid state which is called as melting.
