Answer:

D) Van der Waals

Explanation:

Given that the geometry is linear, one finds that the C = O bonds cancel out any polar effects due to the linear geometry ( O = C = O )and gives the molecule a net dipole of zero. Interactions are therefore dependent upon dispersion forces that are classified as Van der Waal Forces or London Forces.

if a 500.0-g block of metal absorbs 5,016J of heat when its temperature changes from 20.00 Celcius, what is the specific heat?

ZanzabumX [31]

Correction: The temperature change is from 20 °C to 30 °C.

Answer:
Cp = 1.0032 J.g⁻¹.°C⁻¹

Solution:

The equation used for this problem is as follow,

Q = m Cp ΔT ----- (1)

Where;
Q = Heat = 5016 J

m = mass = 500 g

Cp = Specific Heat Capacity = ??

ΔT = Change in Temperature = 30 °C - 20 °C = 10 °C

Solving eq. 1 for Cp,

Cp = Q / m ΔT

Putting values,
Cp = 5016 J / (500 g × 10 °C)

Cp = 1.0032 J.g⁻¹.°C⁻¹

According to the Law of Conservation of Mass, how much water is produced if 22.5 g of

nadezda [96]

Answer: The amount of water produced is 9.3 grams

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

$CH_4+2O_2\rightarrow CO_2+2H_2O$

mass of reactants = mass of methane + mass of oxygen = 22.5 g + 35.7 g = 58.2 g

mass of products = mass of carbon dioxide + mass of water = 48.9 g + mass of water

48.9 g + mass of water = 58.2 g

mass of water = 9.3 g
