(Answer) 0.166 moles of copper (I) nitride are needed.

Mass of copper (I) oxide = 35.7 g

Moles of copper (I) oxide formed by the reaction = (Mass / molar mass)

= ( 35.7 g / 143.09 g/mol ) = 0.25 moles

According to the balanced chemical equation,

mole ratio of copper (I) nitride and copper (I) oxide = 2: 3

Therefore, moles of copper (I) nitride needed to form 0.25 moles of copper (I) oxide = (2/3 x 0.25) moles = 0.166 moles.

Thus, 0.166 moles of copper (I) nitride are needed to form 0.25 moles of copper (I) oxide.

Anna wants to buy a one carat diamond. One carat equals 200 mg. If a diamond is 0.600 carat, what is the mass of the diamond in
Alexxx [7]

The mass of the diamond is 7.056 × 10⁻³ oz.

<em>No. of grams</em> = 1 ct × (200 mg/1 ct) × (1 g/1000 mg) = 0.2 g

<em>No. of pounds</em> = 0.2 g × (1 kg/1000 g) × (2.205 lb/1 kg) = 4.410 × 10⁻⁴ lb

<em>No. of ounces</em> = 4.410 × 10⁻⁴ lb × (16 oz/1 lb) =  7.056 × 10⁻³ oz

What is the number of electrons shared between the atoms in I2 molecule (That is an i not a 1)
labwork [276]
Iodine is one of seven elements that usually form as diatomic molecules. These other "diatomics" are O_2, H_2, F_2, Br_2, N_2, and Cl_2. They typically bond to themselves.

Iodine has seven valence electrons. Using valence shell electron pair repulsion (VSEPR) theory, we can predict the Lewis dot structure for I_2. We see there are fourteen electrons, and we can make a covalent bond, leaving three lone pairs on each atom. The bond replaces two electrons, so the number of electrons shared is two.

Calculating the expected pH of the buffer solution: Given that the pKa for Acetic Acid is 4.77, calculate the expected pH of the
ser-zykov [4K]

Answer:

pH=4.77

Explanation:

From the question we are told that:

pKa for Acetic Acid pK_a= 4.77

Therefore

For Equal Concentration of acetic acid and acetatic ion

CH_3COOH=CH_3COO^-

Generally the Henderson's equation for pH value is mathematically given by

pH=pK_a+log\frac{base}{acid}

pH=4.77+log\frac{CH_3COO^-}{CH_3COOH}

pH=4.77+log1

pH=4.77
