Answer:

Explanation:

Explanation:

If Earth’s temperatures increase, it would likely have these effects:

The East Coast of the United States will face an increased risk of hurricanes as warmer waters increase evaporation.

The polar region will experience melting ice caps, which will cause sea levels to rise.

Warmer water in the Great Lakes will cause heavier lake-effect snows.

In the Pacific Ocean, heating of the water will cause a change in convection currents.

Hot, dry conditions will increase the risk of wildfires in the forests of California.

In the Himalayas, animal and plant life will migrate to higher ground to live.

The coastal regions of Europe will be at greater risk of flooding because of rising sea levels.

What mass of HCL, in grams, is required to react with 0.610 g of al(oh)3 ?
kompoz [17]

Answer: 0.8541 grams of HCl will be required.

Explanation: Moles can be calculated by using the formula:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Given mass of Al(OH)_3 = 0.610 g

Molar mass of Al(OH)_3 = 78 g/mol

\text{Number of moles}=\frac{0.610g}{78g/mol}

Number of moles of Al(OH)_3 = 0.0078 moles

The reaction between Al(OH)_3 and HCl is a type of neutralization reaction because here acid and base are reacting to form an salt and also releases water.

Chemical equation for the above reaction follows:

Al(OH)_3+3HCl\rightarrow AlCl_3+3H_2O

By Stoichiometry,

1 mole of  Al(OH)_3 reacts with 3 moles of HCl

So, 0.0078 moles of Al(OH)_3 will react with \frac{3}{1}\times 0.0078 = 0.0234 moles

Mass of HCl is calculated by using the mole formula, we get

Molar mass of HCl = 36.5 g/mol

Putting values in the equation, we get

0.0234moles=\frac{\text{Given mass}}{36.5g/mol}

Mass of HCl required will be = 0.8541 grams

Calculate the mass of xenon difluoride gas with a volume of 0.223 L, pressure of 0.799 atm and temperature of 47.0 oC.
Greeley [361]

The mass of the gases can be determined by the moles of the gas in the ideal equation. The mass of xenon difluoride at 0.799 atm is 0.011 gms.

<h3>What is an ideal gas equation?</h3>

An ideal gas equation gives the moles of the substance from the temperature, volume, and pressure of the gas. The ideal gas equation can be shown as:

n = PV ÷ RT

Here, n = mass ÷ molar mass

Given,

Volume of xenon difluoride (V) = 0.223 L

Pressure of xenon difluoride (P) = 0.799 atm

Temperature of xenon difluoride (T) = 320.15 Kelvin

Gas constant (R) = 8.314 J⋅K⁻¹⋅mol⁻¹

The moles of the gas is calculated as:

n = PV ÷ RT

= 0.223 × 0.799 ÷ 8.314 × 320.15

= 0.1781 ÷ 2661.72

= 6.69 × 10⁻⁵ moles

Mass is calculated as:

169.29 × 6.69 × 10⁻⁵ = 0.011 gm

Therefore, 0.011 gms is the mass of xenon difluoride.

Which of the following solutions would have the lowest freezing point?
Paul [167]

B. 3.0 mol·L⁻¹ NaCl

Explanation:

Freezing point is a colligative property: it depends only on the number of particles in solution.

The for freezing point depression ΔT_f is

ΔT_f = iK_fb

where

i = the number of moles of particles available from one mole of solute

K_f = the molal freezing point depression constant

b = the molal concentration of the solute

All your solutions are aqueous NaCl. They differ only in their concentrations.

Thus, the most concentrated solution will have the greatest freezing point depression and the lowest freezing point.

Is smelting a chemical or physical process?
nydimaria [60]
Smelting is chemical because you are refining the ore. Also when you heat substances, there is a chance you will decompose some compounds in the process.
