Answer: A covalent bond consists of 2 electrons.

Explanation:

A covalent bond is defined as the bond which is formed by the sharing of electrons between the atoms forming a bond. For Example: HCl is a covalent bond which is formed by the sharing of electrons between hydrogen and chlorine atoms.

Covalent bond can be of three types:

Single covalent bond: This bond consists of 2 electrons.
Double covalent bond: This bond consists of 4 electrons
Triple covalent bond: This bond consists of 6 electrons.

Hence, a covalent bond consists of 2 electrons.

Please help me balance: _NaNO3 + _PbO_ ➡️ Pb(NO3)2 + _Na2O

KengaRu [80]

Answer:

The balanced reaction is given by,

$2NaN(O)3 + PbO$ ⇒ $Pb(NO3)2 + Na2O$

Explanation:

The reaction is as given.

Lets count the number of each elements in the reaction.

In reactant side, number of sodium atoms are 1 , lead are 1, nitrogen are 1 and oxygen are 4.

in product side, number of sodium atoms are 2 , lead are 1 , nitrogen are 2 and oxygen are 7.

So we need to balance sodium and oxygen atoms in the reaction.

There is deficient of sodium and oxygen atoms on reactant side.

Thus, multiply (NaNO3) by 2.

Thus, sodium atoms become 2 , nitrogen 2 and oxygen 6. Total 7 oxygen atoms.

Thus, the balanced reaction is,

$2NaN(O)3 + PbO$ ⇒ $Pb(NO3)2 + Na2O$

there are two processes involved in photosynthesis- the light reactions and the dark reactions- what is the end result of the li

GarryVolchara [31]

In light reactions there is successful photosynthesis due to the fact one of the primary reactants for photosynthesis in the first place. At the end of the light reaction, there will be the normal photosynthesis products formed which are glucose and oxygen. For the dark reaction no products will be formed

How much of 45 grams of pu 234 remains after 27 hours if it’s half life is 4.98 hours

nadya68 [22]

Answer:

1.07 g

Explanation:

Half-life of Pu-234 = 4.98 hours

Initially present = 45 g

mass remains after 27 hours = ?

Solution:

Formula

mass remains = 1/ 2ⁿ (original mass) ……… (1)

Where “n” is the number of half lives

To find "n" for 27 hours

n = time passed / half-life . . . . . . . .(2)

put values in equation 2

n = 27 hr / 4.98 hr

n = 5.4

Mass after 27 hr

Put values in equation 1

mass remains = 1/ 2ⁿ (original mass)

mass remains = 1/ 2^5.4 (45 g)

mass remains = 1/ 42.2 (45 g)

mass remains = 0.0237 x 45 g

mass remains = 1.07 g

What is the relationship between concentration and rate of reaction?

marshall27 [118]

Explanation:

The answer is directly proportional, because when there is more concentration their will more reactants to react fast diring the chemical reaction which increases the rate of chemical reaction. 

So, we can state that the relationship between them are directly proportional. 

Hope it helps...
