Answer:

The answer to the question is

The specific heat capacity of the alloy = 1.77 J/(g·°C)

Explanation:

To solve this, we list out the given variables thus

Mass of alloy = 45 g

Initial temperature of the alloy = 25 °C

Final temperature of the alloy = 37 °C

Heat absorbed by the alloy = 956 J

Thus we have

ΔH = m·c·(T₂ - T₁) where  ΔH = heat absorbed by the alloy = 956 J, c = specific heat capacity of the alloy and T₁ = Initial temperature of the alloy = 25 °C , T₂ = Final temperature of the alloy = 37 °C  and m = mass of the alloy = 45 g

∴ 956 J = 45 × C × (37 - 25) = 540 g·°C×c  or

c = 956 J/(540 g·°C) = 1.77 J/(g·°C)

The specific heat capacity of the alloy is 1.77 J/(g·°C)

A vial of amoxicillin contains 500 mg in 2.0 mL of solution. What volume of the solution contains 180 mg of the drug
Tom [10]
<span>0.72 mL of solution will have 180 mg of amoxicillin. For this problem, you need to calculate the equivalent ratio of volume as to the ratio of amoxicillin. So 180/500 = X/2.0 Multiply both sides by 2 2 * 180/500 = X 360/500 = X 18/25 = X 0.72 = X So you need 0.72 mL of solution to get 180 mg of the drug.</span>

Can chlorine form two bonds?
pychu [463]

Double bonds are not formed by chlorine. To complete its octet, oxygen requires two bonds (two single bonds or one double bond) and two lone pairs.

Chlorine can only form single bonds unless, for instance, it is bonded to oxygen (ClO3H), in which case, the oxygen forces chlorine to form double bonds.

The chemical element chlorine has the atomic number 17 and the symbol Cl. The second-lightest halogen, fluorine is situated between bromine and fluorine in the periodic table and has most of its features in the middle. At room temperature, chlorine is a gas that is yellow-green.
