5 electrons

Hydrogen shares its only electron with Carbon to get a full valence shell. Now Carbon has 5 electrons. Because each Carbon atom has 5 electrons--1 single bond and 3 unpaired electrons--the two Carbons can share their unpaired electrons, forming a triple bond

liq [111]

Answer:

When cinnamic acid react with bromine ,addition reaction rapidly occur on alkene functional group to form dibromo product

Explanation:

Phenyl ring is an aromatic hydrocarbon ,when aromatic hydrocarbons react with Cl2,Br2 or KMnO4 no reaction occur ,where as unsaturated hydrocarbon like alkene react .Aromatic hydrocarbon with these reagents undenr different conditions undergoes subtituition reaction.They react with bromine in presence of lewis acid catalyst ferric bromide.

b. Determine the molecular formula of a molecule with an empirical formula NH2and a molar mass of 32 g/mol.

VladimirAG [237]

I'm taking this lesson now, so imma help u ( if u need anything else ask me)

so given Molar mass= 32 g/mol
molar mass= (empirical formula) n
32 = (14x1 + 2x1) n
32 = 16 n , so n= 2
so, molecular formula= N2H4

3 Cu + 8HNO3 g 3 Cu(NO3)2 + 2 NO + 4 H2O

liubo4ka [24]

24.25 moles of NO can be produced using 97 moles of HNO3.

<h3>What is balanced chemical equation?</h3>

Equal numbers of atoms from various elements are present in both the reactants and the products in balanced chemical equations. Varied elements' atom counts in the reactants and products of unbalanced chemical equations are different.

3 Cu + 8HNO3 g → 3 Cu(NO3)2 + 2 NO + 4 H2O

The number of moles consumed can be calculated using comparing with coefficients in the balanced reaction .

So , from above eq we get that 8 moles of HNO3 are consumed to make 2 moles of NO.

⇒ 8 HNO3⇔2 NO

⇒ 1 HNO3⇔ 1/4 NO

This means that for each mole of HNO3 produces 1/4 moles of NO.

So , for 97 moles of HNO3 , $\frac{1}{4} *97$ moles of NO can be made,

So, total moles of NO made are 24.25 moles.

Name the type of bond in organic chemistry that corresponds to a glycoside bond

Semenov [28]

Answer:

covalent bond

Explanation:

The bond which is most common in the organic molecules is the covalent bond which involves sharing of the electrons between the two atoms.

Glycosidic bond, also known as glycosidic linkage is type of the covalent bond which joins carbohydrate molecule to other group that may not or may be a carbohydrate.

Glycosidic bond is the bond which is formed between hemiacetal or hemiketal group of the saccharide and hydroxyl group of compounds like alcohol.

1CuCl2 + 2Na(NO3) --> 1Cu(NO3)2 + 2NaCl

vivado [14]

Answer:

13.45 grams of NaCl will be produced

Explanation:

Given:

Mass of CuCl2 = 15 grams

Molar mass of CuCl2 = 134.5 g/mol

Mass of Na(NO3) = 20grams

Molar mass of Na(NO3) = 85 g/mol

To find:

Amount of Sodium chloride produced = ?

Solution:

No of moles of CuCl2 = 15/134.5 = 0.11 moles

No of moles of Na(NO3) = 20/85 = 0.23 moles,

1CuCl2 + 2Na(NO3) --> 1Cu(NO3)2 + 2NaCl

from the reaction, 1 mole of copper chloride reacts with 2 mole of NaNO3 to produce 2 moles of sodium chloride.

Hence, 0.11 mole of copper chloride will react with 0.23 mole of NaNO3 to produce 0.23 moles of sodium chloride.

Mass of 0.23 moles of NaCl = 0.23 × M.M of NaCl

(Molar mass of NaCl = 58.5)

Mass of 0.23 moles of NaCl = 0.23 × 58.5 = 13.45 grams
