All of the energy from the reactants will be lost to the surroundings.The energy found in the reactants remains in the system, and the reactants also take energy from the

surroundings is true of energy in reactants during endothermic reaction.

<h3>What is Endothermic reaction?</h3>

Endothermic reaction is a reaction in thermochemistry where the reactants absorb heat from the surrounding to form the products.

In an endothermic reaction, the products have more energy than the reactants, that is they absorbed more energy. The reactants have less energy,that is they loss energy . Therefore, the change in enthalpy is positive, heat is absorbed from the surroundings during the reaction.

Therefore, All of the energy from the reactants will be lost to the surroundings.

The energy found in the reactants remains in the system, and the reactants also take energy from the

surroundings is true of energy in reactants during endothermic reaction.

V\3. The atomic masses of any two elements contain the same number of _
SashulF [63]

a. atoms

Explanation:

Let's take as example carbon and lead. Carbon have an atomic mass of 12 a.m.u while lead have an atomic mass of 207 a.m.u. Value of atomic masses are the same with as the value of molar masses. So carbon have a molar mass of 12 g/mole while lead have a molar mass of 207 g/mol.

Avogadro's number it tell us that in 1 mole of particular substance there are 6.022 × 10²³ particles. Taking in account this, in 12 g of carbon there are 6.022 × 10²³ carbon atoms and in 207 g of lead there are 6.022 × 10²³ lead atoms atoms.

The atomic mass of any two elements contain the same number of atoms.

7. A sample of a compound that contains only chlorine and oxygen reacts with excess hydrogen to produce 0.233 grams of hydrochlo
Snowcat [4.5K]

Answer:

ClxOy + H2 > HCl + H2O

HCl = 0.233/37 = 0.006 mol H2O = 0.403/180.02 mol

HCl = 0.006/0.022 H2O = 0.022/0.006

= 1 = 4

Cl2O4 + 5H2 > 2HCl + 4H2O

I'm think that's the answer

Salsk061 [2.6K]

Answer:

C.5

Explanation:

A number of electrons present in valence shell of penultimate Shell represents the group of elements.

For s block elements: no.of group=number of valence shell electron.

p block elements: no. of group= 2 + 10 + number of valence electrons.

d block elements: no. of group= number(n-1)d electrons + number of electrons in nth shell.

Here, the differential electron is in p orbital hence, it belongs to p block

No. of group= 2+ 10 + 3=15 i.e 15th group or VA group.
