Answer: Option (C) is the correct answer.

Explanation:

Chemical formula of water is $H_{2}O$ and since, it is formed by combining two non-metals then sharing of electrons take place between the them.

As oxygen is more electronegative in nature so it will attract the valence electrons of hydrogen atom towards itself. Due to this partial positive charge will develop on the hydrogen atom and a partial negative charge will develop on the oxygen atom.

Hence, water is a polar covalent compound. And, a covalent compound is weak as compared to an ionic bond therefore, water has low melting point.

Thus, we can conclude that the statement water is more likely a covalent compound because water has a low melting point, BEST predicts whether water is an ionic compound or a covalent compound.

Answer:

Water is more likely a covalent compound because water has a low melting point.

Explanation:

Ionic compounds are formed from strong electrostatic interactions between ions, which result in higher melting points.

Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties such as lower melting points.

If this decay has a half life of 2.60 years, what mass of 72.5 g of sodium 22 will remain after 15.6 years

Vlad1618 [11]

Sodium-22 remain : 1.13 g

<h3>Further explanation </h3>

The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.

Usually, radioactive elements have an unstable atomic nucleus.

General formulas used in decay:

$\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{T/t\frac{1}{2} }}}$

T = duration of decay

t 1/2 = half-life

N₀ = the number of initial radioactive atoms

Nt = the number of radioactive atoms left after decaying during T time

half-life = t 1/2=2.6 years

T=15.6 years

No=72.5 g

$\tt Nt=72.5.\dfrac{1}{2}^{15.6/2.6}\\\\Nt=72.5.\dfrac{1}{2}^6\\\\Nt=1.13~g$

After observing (you can repeat the process more than once), write a general statement explaining how reducing the volume change

ad-work [718]

Answer:

The correct answer is that both molecular motion, pressure and temperature increase as volume reduces.

Explanation:

A reduction in volume changes the molecular motion, temperature and pressure of the system. When the volume of the container decreases, this causes the pressure to increase, the temperature to increase and the molecular motion to increase. This is because a liquid and a solid are incompressible, so by reducing the volume of a gas, the molecules increase their movement as the temperature of the system increases, which is due to the increased pressure applied to reduce the volume of the system.

To present his data on the <span>solubility of three different salts in water at 22°C, bar graph should be used since there are different salts and the only variable is the type of salt used. Line graph and scatter plot use two coordinates or variables and is common to comparing data using the same sample while using histogram to find out data distribution is irrelevant.</span>
