Answers

Answer 1

The four items that change in the hazard communication standard for chemical labels and SDS

Product identifier.Signal word.Hazard statement.Pictograms.Precautionary statement.

This is further explained below.

What is the hazard communication standard?

Generally, The Hazard Communication Standard (HCS) was developed to ensure that employees have the "right to know" about any possible dangers that may be related to the work that they do. The HCS is a preventative strategy that is meant to distribute information to employees and employers about the health dangers that are associated with the chemicals that they handle and the protection that is necessary.

In conclusion, Hazard communication labels and SDS product identifiers have undergone four changes as a result of the new standard. The term serves as a signal to the driver. There is a risk. Pictograms. Statement of caution.

Match each term to its description. Match Term Definition Excess reactant A) Amount of product predicted to be produced by the given reactants Limiting reactant B) Reactant that can produce more of the product Theoretical yield C) Reactant that can produce a lesser amount of the product

Answers

Answer:

Excess reactant - Reactant that can produce more of the product

Limiting reactant - Reactant that can produce a lesser amount of the product

Theoretical yield - Amount of product predicted to be produced by the given reactants

Explanation:

In every chemical reaction, there is a limiting reactant and there is an excess reactant.

The limiting reactant determines the amount of product obtained. It is the reactant that produces a lesser amount of the product.

The excess reactant is known to be the reactant that produces a greater amount of the product.

The theoretical yield is calculated using the limiting reactant and is the amount of product predicted to be produced by the given reactants.

Explanation:

Option D is the correct Lewis structure of ozone.

Ozone is known to be an allotrope of oxygen which has three atoms of oxygen.

In the Lewis structure of ozone, one pair of oxygen is actually double-bonded while the other is single-bonded. In this structure, two oxygen atoms carry charges. In the drawing the Lewis structure of ozone, we discover that one oxygen atom of the ozone has a -1 charge and while another oxygen atom of the ozone has a +1 charge.

20 mL of NaOH solution was added to the conical flask. Indicator was added & titrated with 0.1 M HCl solution. The HCl used in the titration was read as 18.3 mL. What is the molar concentration of NaOH?

Answers

Answer:

[NaOH] = 0.1 Molar ... Note => the brackets around formula;i.e., "[ ]" is generally accepted in the chemistry community as concentration in Molar terms.

Explanation:

The metathesis rxn, or double replacement rxn, equation is:

(Molarity x Volume) of acid = (Molarity x Volume) of base, or

(M·V)acid = (M·V)base => M(base) = M·V(acid)/V(base)

= 0.1M × 18.3ml / 20ml = 0.0915M(base) = 0.1M (1 sig-fig) = [NaOH]

25°C?

-
can anyone help me?!!!??!?!​

Answers

Answer:

No, It would be a unsaturated solution

Explanation:

The solubility of a compound gives us information about how a compound may dissolve or not in a determinate solvent.

In this case we have Z, which in 25 °C the solubility of this compound is 40g/100 mL water. This means that if we have 60 g of Z and try to dissolve it in 100 mL of water, only 40 g of Z will solve and the remaining 20 g will be in the water as precipitate or remaining solid.

Now if you just put 40 g of Z in 100 mL water, it will dissolve completely in water, and in this case, we have a saturated solution. A saturated solution is when you dissolve a determinated quantity of a solute in a determinated quantity of solvent, without remaining of solid or excess of solvent.

According to this explanation, we now have 120 g of Z. To make a saturated solution of Z with this quantity, well, let's do math. If 40 g dissolves in 100 mL, then 80 g would be 200 mL and 120 g would have to be 300 mL of water. But in this case, we have 450 mL of water, we have more than 300 mL, an excess of water, so, the 120 g will dissolve but it's dissolved in more than the needed quantity to be a saturated solution, therefore, we have an unsaturated solution of Z (more solvent than the needed).

If one of the cars began with 5.6 liters of gasoline and oxygen, how much water and carbon dioxide do you think would be produced from that gasoline and oxygen?

Answers

Answer

5.6 L

Explanation:

whatever you start with, you end with the same amount.

(LAW OF CONSERVATION)

The amount of oxygen and gasoline that can be produced is 5.6 liters

The question above is answered with the law of conversation of mass. This law of conversation of mass states that  no form of energy can be destroyed, instead it is changed from one form to another type of form.

In this law, it is expected that you end with the same amount you started with. According to the question above, since the amount that you started  with is 5.6 liters then you will end with 5.6 liters also.

When silver nitrate (AgNO3) dissolves in water, the temperature of the solution decreases.
Explain your answer

Answers

Answer:

The enthalpy of solution for AgNO3 is positive because the temperature of the solution decreases (the dissolution is endothermic). Hsol = Hsolute + Hsolvent + HmixHsolute and Hsolvent are endothermic because energy is required to overcome intermolecular forces and separate solute and solvent particles.

Answer:

the enthalpy of solution for agno3 is positive because the temperature of the solution decreases. (the dissolution is endothermic.)

Delta H sol=delta HSolute +delta H solvent +delta H mix

HSolute and H solvent are endothermic because energy is required to overcome intermolecular forces and separate solute and solvent particles.

H mix is exothermic because energy is released when intermolecular forces form between solute and solvent particles.

if the overall enthalpy of solution is positive, then HSolute + H solvent must be larger in magnitude than H mix.

Why is 1/t used as a measure of rate of reaction?​

Answers

1/t denotes that the reaction order is of the first order. That is, the rate of reaction is directly proportional to the concentration of the reactant. Because scientists use standard units, 1/t equals one divided by one second.

What do you mean by first order reaction ?

The term first order reaction is defined as a chemical reaction in which the reaction rate is linearly dependent on the concentration of only one reactant.

In other words, a first-order reaction is a chemical reaction in which the rate varies as the concentration of only one of the reactants changes.

Because a reaction that takes longer to complete is obviously a slower reaction. A fast reaction is one that takes less time to complete. 1/t simply provides a quantitative value for comparing reaction rates.

Thus, 1/t denotes that the reaction order is of the first order.
