Na = 2 atoms

Cl = 2atoms

F = 2 atoms

Given

Skeleton equation(unbalanced equation) :

NaCl+F2⇒NaF+Cl2

Required

The number of atoms

Solution

We balance the reactions to find the reaction coefficient, which is then used to calculate the number of atoms in the reactants and products

Balanced equation

2NaCl + F2 → 2NaF + Cl2

A balanced reaction will show that the number of atoms in the reactants and products is the same

Na = 2 atoms

Cl = 2atoms

F = 2 atoms

Na = 2 atoms

F = 2 atoms

Cl = 2 atoms

Answer:

decreases

Explanation:

I'm hope it's correct

When there is an exothermic reaction so here the average kinetic energy of the particles of matter ib the products is option 1. decrease.

In terms of thermochemistry, an exothermic reaction means the reaction where the total standard enthalpy should change so ΔH⚬ is negative. Also it should be release heat.

So based on this, When there is an exothermic reaction so here the average kinetic energy of the particles of matter ib the products is option 1. decrease.

Explanation:

This law states that a still object will stay still unless a force pushes or pulls it. A moving object will stay moving unless a force pushes or pulls it. Gravity and friction are forces that constantly push and pull the "stuff" on earth. So, when we roll a ball, it slowly comes to a stop.

Answer:

They may have different phenotypes because of differences in their environments, such as nutrition and healthcare. Why might genetically identical twins have different phenotypes?  Any genes on the same chromosome could be linked genes, whereas only genes on sex chromosomes can be sex-linked genes.

Explanation:

Due to the effects of the environment, genetically identical twins might have different phenotype.

The qualities or visible characteristics of an organism are its phenotype. It depends on how the environment and the genotype, or genetic code, of the organism interact.

Although human monozygotic twins as well as other genetically identical species may share startling physical similarities, they frequently differ in key characteristics, such as complicated diseases. The effects of the environment have generally been blamed for this variance across organisms with essentially identical chromosomal DNA sequences.

Therefore, due to the effects of the environment, genetically identical twins might have different phenotype.

Answer:

Explanation:

The balanced chemical equation is Cl2 + 2KBr → 2KCl + Br2. The amount of bromine is calculated as follows:

11.0 g KBr (1mol KBr/119.002g KBr * 1mol Br2/2mol KBr * 159.808g Br2/1mol Br2= 7.39 g Br2.)

Answer:

The correct answer is - tin.

Explanation:

Tin is the element that is mixed with copper to make bronze as bronze has many unique properties such as crisp sound quality and hardness. The hardness of the bronze allows them to make a good quality sound is come by adding tin to copper restricts the free flow of electrons of the copper atoms.

The pure metals have molecules present in an orderly manner and allow the electrons to free flow. This is why bell makers use bronze as it does not allow electrons to move freely which makes it hard and makes a good sound.

The amount of molecules= 3.01 x 10²⁴

Given

5 moles of N2

Required

The number of molecules

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

For 5 moles :

= 5 x 6.02 x 10²³

= 3.01 x 10²⁴

Answer:

5 hours.

Explanation:

Given that,

Initial time, [tex]T_i=6\ pm[/tex]

Final time, [tex]T_f=11\ pm[/tex]

We need to find how much time did it take the car to arrive.

Time =  final time-initial time

= 11 pm - 6 pm

= 5

So, it takes 5 hours by car to arrive.

Answer:

1: The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his hypothesis was rejected by many for lack of any motive mechanism. 2: The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.

Answer:

1. D

2. C

Explanation:

1. Although now accepted, the theory of continental drift was rejected for many years, with evidence in its favor considered insufficient. One problem was that a plausible driving force was missing. A second problem was that Wegener's estimate of the speed of continental motion, 250 cm/year, was implausibly high.

2.The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.
