The moon is what makes currents so if there was no moon there would be no current in our oceans. The way it makes currents is from the gravitational pull.

If a chemical with a toxicity level of 1 is mixed with a different chemical with a toxicity level of 1, the combined effect of e
ollegr [7]

Answer:

c. antagonism

Explanation:

The toxic effect is that produced by one or several toxic agents on an organism, population or community that is manifested by biological changes. Its degree is assessed by an intensity or severity scale and its magnitude is related to the dose (amount of substance administered, usually expressed per unit of body weight) or the concentration (substance applied in the medium) of the toxic agent.

The effect can be:

- Quantum: consisting of the presence or absence of a characteristic (eg death or existence of tumors).

- Lethal: death by direct action as a result of exposure to a certain concentration of a toxic agent.

- Sublethal: occurs below the level that causes death as a direct result of exposure to a certain concentration of a toxic agent.

- Acute: that caused by the action of chemical substances on living organisms, which manifests rapidly and severely (after a short period of exposure: 0 - 96 h, typically.).

- Chronic: one that occurs, in general, after a prolonged period of exposure (usually manifests after days or years, depending on the species).

- Additive: the magnitude of the effect or simultaneous response of two or more substances is equal to the sum of the effects or responses of each.

- Combined: when two or more substances applied at the same time produce different effects or have different modes of action.

- Enhancement or synergism: when the toxicity of a mixture of chemical agents is greater than expected by the simple sum of the toxicities of the individual agents present in the mixture.

- Inhibition or antagonism: when the toxicity of a mixture of chemical agents is lower than expected by the simple sum of the toxicities of the individual agents present in the mixture.

A chemistry teacher adds 50.0 mL of 1.50 M H2SO4 solution to 200 mL of water. What is the concentration of the final solution? U
Aleks [24]
Hello!

The concentration of the final solution when a<span> chemistry teacher adds 50.0 mL of 1.50 M H2SO4 solution to 200 mL of water is 0,3 M

To calculate that, you'll need to use the dilution law, where initial and final concentrations are M1 and M2 respectively, and initial and final volumes are V1 and V2, as shown below. Keep in mind that the final volume is the sum of the 200 mL of water and the 50 mL of H</span>₂SO₄ that were added by the teacher. 

M2= \frac{M1*V1}{V2}= \frac{1,50 (mol H_2SO_4/L)*50mL}{(50 mL + 200 mL)}=0,3(mol H_2SO_4/L)

Have a nice day!

On a lab exam, you have to find the concentrations of the monoprotic (one proton per molecule) acids HA and HB. You are given 43
Keith_Richards [23]

HA and HB are present in concentrations of 0.182 M and 0.153 M, respectively.

<h3>What kind of acids are monoprotic?</h3>

Monoprotic acids include benzoic acid (C6H5CO2H), acetic acid (CH3CO2H or HOAc), nitric acid (HNO3), and hydrochloric acid (HCl).

<h3>How can you tell if a substance is monoprotic?</h3>

Any acid with only one hydrogen atom in its formula is called a monoprotic acid, while some acids with multiple hydrogen atoms may also fall under this category. In other words, while all monoprotic acids contain only one hydrogen, not all single-hydrogen acids are monoprotic.

<h3>Do monoprotic acids have a low acidity?</h3>

Because it easily loses its hydrogen ion in solution, the monoprotic acid HBr is regarded as being strong.
