What is a limiting reagent? A.) The reactant that is used up first in a reaction B.) The reactant that is used the least reactive in a reaction C.) the reactant with the smallest coefficient in the equation D.) the reactant with the largest coefficient in the equation

Answers

Answer 1

Answer: A.) The reactant that is used up first in a reaction

Answer 2

The reactant that is totally consumed during a reaction, or the limiting reagent, decides when the process comes to an end. A limiting reagent is the reactant that is used up first in a reaction. Therefore, option A is correct.

What is a limiting reagent?

A reactant that is completely consumed at the end of a chemical reaction is known as the limiting reagent. Since the reaction cannot proceed without this reagent, the amount of product that can be produced is constrained.

The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.

The terms limiting reagent and limiting agent may also be used to describe the limiting reactant.

Thus, option A is correct.

Santiago's car has an overall average speed of 25 cm/s. If he could increase his car's overall average speed by 10%, what would his car's new overall average speed be?

Answers

Given:

The overall average speed = 25 cm/s.

The overall average speed increased by 10%.

To find:

The new overall average speed.

Solution:

We have,

Overall average speed = 25 cm/s.

The overall average speed increased by 10%. So, the new average speed is

New overall average speed = Initial average speed + 10% of initial  overall average speed

[tex]\text{New overall average speed}=25+\dfrac{10}{100}\times 25[/tex]

[tex]\text{New overall average speed}=25+2.5[/tex]

[tex]\text{New overall average speed}=27.5[/tex]

Therefore, the new overall average speed is 27.5 cm/s.

Climates at different latitudes are similar to one another.

Explanation:

The choice that is not a proof of Wegener's concept of concept of continental drift is that climates at different latitudes ae similar to one another.

Wegener did not use climatic evidence to proof continental drift. He did use fossils found on different continents such as the mesosaurus to propose the theory of continental drift. Wegener also used evidence of glacial sediments to justify his claims. He also fitted the earth into a giant puzzle.

39.098 gk
21.62 g B
9.0122 g Be

Answers

Explanation:

9.0122 g be Maybe, sorry i don't think so

In the above , the sample of B 21.62 g of boron contains the most atoms because it has approximately 2 moles, while the other samples have only 1 mole each.

What is atoms

The molar mass of each element can be found on the periodic table.

The molar mass of Mg (magnesium) is about 24.305 g/mol.The molar mass of K (potassium) is about 39.098 g/mol.The molar mass of B (boron) is approximately 10.81 g/mol.The molar mass of Be (beryllium) is about  9.0122 g/mol.

To calculate the number of moles in each sample, we divide the mass of each sample by its respective molar mass:

For Mg: Number of moles = 24.305 g / 24.305 g/mol = 1 moleFor K: Number of moles = 39.098 g / 39.098 g/mol = 1 moleFor B: Number of moles = 21.62 g / 10.81 g/mol ≈ 2 molesFor Be: Number of moles = 9.0122 g / 9.0122 g/mol = 1 mole

Therefore, the sample with 21.62 g of boron (B) contains the most atom
