What are the hazards, if any of the reactants AgNO3, and K2CrO4?

Answers

Answer 1

Answer: This is what i wrote in my notebook: (for AgNO3)
Health Hazards Acute and Chronic: ACUTE:
INHALATION - MAY CAUSE SEVEREIRRITATION TO MUCOUS MEMBRANES.
SKIN - MAY CAUSE SEVERE IRRITATION.
EYE - MAY CAUSE SEVERE IRRITATION.
CHRONIC: INHALATION, SKIN &INGESTION - MAY CAUSE ARSYRIA.Explanation of Carcinogenicity:THIS COMPOUND CONTAINS NO INGREDIENTS ATCONCENTRATIONS OF 0.1% OR GREATER THAT ARE CARCINOGENS OR SUSPECTCARCINOGENS.

AgNO3 + K2CrO4 = Ag2CrO4 + KNO3

The correct answer is the gamma ray. It has the most penetration power and will pass through a number of things. Also, a gamma ray has shorter wavelength therefore higher energy from the equation, Energy = hc/wavelength.

Considering the law of conservation of mass, if 56 g samples of solid iron (Fe) reacts with 24 g of oxygen (O2), how many grams of Iron Oxide (FeO) are obtained?

Answers

Answer:

62_grams of FeO

Explanation:

Molar mass of Fe = 55.845_g/mol

Molar mass of O2 = 15.999_g/mol

From law of conservation of mass

2 moles of Fe combines with one mole of O2 to form 2 moles of FeO

Number of moles of Fe and O2 present = mass/(molar mass) = 56/55.845~1

and 24/16 = 1.1.5

Therefore

1 part of Fe will react with 0.5 part of one mole of O2

which is 54_g of Fe reacts with 8_g to form 54+8 = 62_grams of FeO

D. Each bond is a single bond. Allowing all 4 valence electrons in the carbon to be taken up by the one valence electron in the four hydrogen atoms.

H2(g) + CO2(g) + 10 kcal H2O(g) + CO(g)In another experiment involving the above reaction at 1,000°C, the equilibrium concentrations were found to be:

H2(g) = 2.0 moles per liter
H2O(g) = 4.0 moles per liter
CO2(g) = 5.0 moles per liter
CO(g) = 4.0 moles per liter

What is the equilibrium constant, Keq, for this reaction?

Answers

The equilibrium contant for the reaction is 1.6. Solution: [H2]=2.0 mol/L [CO2]= 5.0 mol/L [H2O]= 4.0 mol/L [CO]= 4.0 mol/L K = [H2O][CO] / [H2][CO2] K = (4.0)(4.0) / (2.0)(5.0) K = 1.6 Ans [ =1.6 ]
