Answer:

51.79g Li₃P.

Explanation:

Li has a molar mass of 6.94 g (since there are 3, you multiply it 3 times) and P has a molar mass of 30.97 g. 6.94(3) + 30.97 = 51.79g.

Answers

Noble gas located in the region D

Further explanation

Noble gas are located in group 18 in the periodic table consisting of helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), have a stable electron configuration where the valence electrons are 8(full outer shell of electrons), so it is very hard to react because of its stability

If we look at the periodic system of the elements, the noble gases are on the far right, so that in Figure 8 it is located in area D

And the other region :

A : alkali elements(group 1),

B : alkaline earth elements(group 2)

C : halogen elements(group 17)

As shown by the periodic table, why do the elements potassium and sodium have similar chemical properties?

Answers

Hey mate
This is the answer

The elements potassium and sodium have similar chemical properties because they have the same number of valence electrons and form +1 ions.

Which of these are an atom's valence electrons?​

Answers

Answer:

The Outer-most Electron shell contains the valence electrons.

Bonus Info:

Valence Electrons are used by atoms to make ionic bonds.

Answer:

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴.

How many molecules of H2O are in 8.54 moles of H2O?
Select one:
a. 5.14 * 10^24 molecules H2O
b. 2.86 * 10^23 molecules H2O
c. 6.02 * 10^23 molecules H2O
d. 5.14 * 10^23 molecules H2O

Answers

Answer:

[tex]\boxed {\boxed {\sf A. \ About \ 5.14 *10^{24} \ molecules \ H_2O}}[/tex]

Explanation:

To convert from moles to units, we must use Avogadro's Number: 6.022 * 10²³

This tells us the number of units (molecules of water in this problem) in 1 mole of a substance (water). We can use it as a ratio or fraction.

[tex]\frac{6.022 *10^{23} \ molecules \ H_2O}{1 \ mol \ H_2 O}[/tex]

Now, we can multiply this fraction by the moles of water (8.54) given.

[tex]8.54 \ mol \ H_2O*\frac{6.022 *10^{23}\ molecules \ H_2O}{1 \ mol \ H_2 O}[/tex]

When we multiply, the moles of water will cancel out.

[tex]8.54 *\frac{6.022 \ molecules \ H_2O}{1 \ }[/tex]

Since the fraction has a 1 as a denominator, we can remove it. The problem will be a simple multiplication problem.

[tex]8.54*6.022 \ molecules \ H_2O[/tex]

[tex]5.142788*10^{24} \ molecules \ H_2O[/tex]

The original measurement of 8.54 has 3 significant figures (8, 5, and 4). Therefore, we must round our answer to 3 sig figs, which is the hundredth place in this case.

The 2 in the thousandth place tells us to leave the 4 in the hundredth place.

[tex]5.14 *10^{24} \ molecules \ H_2 O[/tex]

There are about 5.14*10²⁴ molecules of water in 8.54 moles.

Answer:

5.14 x 10^24 molecules of H2O.

If the ball is at rest on the soccer field and the four forces shown are applied at the same time, the ball will
А.
move to the left.
B. stay in the same position.
c. accelerate in the direction of the smallest force.
D. resist any change in movement.

Answers

C I think maybe I aM right or 1

Since the rightward force is greater than the leftward force by a magnitude of 10 Newton, the ball will: A. move to the left.

Given the following data:

Upward force = 50 Newton.Downward force = 50 Newton.Rightward force = 30 Newton.Leftward force = 40 Newton.

A net force can be defined as the vector sum of all the forces acting on an object.

Hence, net force is the sum of all forces acting simultaneously on an object.

To determine the direction in which the ball would move if the four forces shown are applied at the same time:

For the downward and upward force:

[tex]Net\;force = 50-50\\\\Net\;force = 0\;Newton[/tex]

For the rightward and leftward force:

[tex]Net\;force = 40-30\\\\Net\;force = 10\;Newton[/tex]

Since the rightward force is greater than the leftward force by a magnitude of 10 Newton, the ball will move to the left.
