Answer:

This isotope has 59 electrons giving it a charge of -2.

Explanation:

To find this we have to understand isotope relates to the mass of the nucleus. This isotope has 59 electrons to counter the protons and give it a negative charge.

When equal molar amounts of the following sets of compounds are mixed in water, which will not form a buffer solution?
krok68 [10]

Nitric acid is a strong acid while the nitrate ion is a very weak base. Nitric acid is able to consume hydroxide ions. However, the nitrate ions present are unable to consume hydronium ions. As a result, the set of compounds does not form a buffer solution.

<h3></h3><h3>What Is Molar Mass?</h3>

A mole is the number of entities present in a substance, such as atoms, molecules, or ions. A mole of any substance is defined as 6.0221023 molecules. Just as we use a standard value to quantify diverse things, such as 1 dozen = 12 items, we utilise the mole to quantitatively calculate the size of the tiniest creatures.

The number of atoms in 12g (0.012 kg) of 12C isotope is equal to the number of particles in 1 mole of the substance. One of the most crucial facts to remember is that the mole of a material always includes the same number of entities regardless of the substance.

Grams smallest to kilograms and milligrams
Anna007 [38]
Grams is smaller than kilograms but larger than milligrams

1g = 0.001 kg
1g = 1000 mg

Grams is an SI unit for mass.

International System of Units (SI Units) are organized body of measurements for physical quantity. They are set to be the norm or global norm scaling for every physical quantity which includes kilogram, meter, second, ampere, kelvin, candela and mole. These measurements then can increase or decrease by the power of ten, multiplied or divided. As said and explained, the SI is helpful in describing objects because

The percent yield of a reaction in which 52 grams of a reactant is expected to yield 30 grams of product is 25%. What is the act
Basile [38]

Answer:

D) 7.5 grams

Explanation:

Hello,

In this case, since the percent yield is defined by:

Y=\frac{m^{actual}}{m^{theoretical}} *100\%

In such a way, since the percent yield is up to 25% and the expected or theoretical amount is 30 g of the product, the actual yield of the reaction is:

m^{actual}=\frac{Y*m^{theoretical}}{100\%}  =\frac{25\%*30g}{100\%} \\\\m^{actual}=7.5g

Therefore the answer is D) 7.5 grams.

Best regards.
