Answer:

Neutrons have a neutral charge

Explanation:

A neutron consists of 3 quarks, 1 up and 2 down. The up quark has a charge of + 2/3e, and the down quarks each have a charge of - 1/3e. So, the charges on the 3 quarks tend to cancel out to produce a neutrally charged particle.

How are the layers of the atmosphere defined?

Juli2301 [7.4K]

The layers of the atmosphere are defined by variations in temperature and pressure with altitude. These include the troposphere (0 to 16 km), stratosphere (16 to 50 km), mesosphere (50 to 80km) and thermosphere (80 to 640km).

Nuclear fusion is the combining of atomic nuclei to produce energy and new types of _____. A. light B. power C. matter D. radiat

Drupady [299]

Answer:

C. matter

Explanation:

When hydrogen atoms collide at very high speeds, the natural electrostatic repulsion that exists between the positive charges of their nuclei is overcome and the atoms fuse, this fusion of light hydrogen atoms produces a heavier element, helium.

<em>In short, nuclear fusion is a process by which nuclear reactions between light elements form heavier elements (up to iron), therefore fusion produces new types of matter. </em>

I hope you find this information useful and interesting! Good luck!

How many moles are in 75 grams of Cl?

laila [671]

Answer:

1.06 mol

Explanation:

$\text{Moles of Cl}_{2} = \text{75 g Cl}_{2}\times \dfrac{\text{1 mol Cl}_{2}}{\text{70.91 g Cl}_{2}} = \text{1.06 mol Cl}_{2}$

A mixture of 0.600 mol of bromine and 1.600 mol of iodine is placed into a rigid 1.000-L container at 350°C.

nata0808 [166]

The equilibrium constant for this reaction at 350°C is determined as 5.85.

<h3>Concentration of each component</h3>

concentration of bromine, C(Br) = 0.6 mol/1 = 0.6

concentration of iodine, C(I) = 1.6 mol/1 = 1.6

<h3>Create an ICE table</h3><h3>What is ICE table?</h3>

An ICE table is a tabular system of keeping track of changing concentrations in an equilibrium reaction.

ICE is an abbreviation that stands for initial, change, equilibrium.

Create ICE table for the reactants and products formed;

Br2(g) + I2(g) ↔ 2IBr(g)

I 0.6 1.6 0

C -1.19 -1.19 1.19

E 0.6 - 1.19 1.6 - 1.19 1.19

E = -0.59 0.41 1.19

<h3>Equilibrium constant </h3>

The equilibrium constant is calculated as follows;

KC = [IBr]²/[Br][I]

KC = (1.19²) / (0.59 x 0.41)

KC = 5.85

Thus, the equilibrium constant for this reaction at 350°C is determined as 5.85.

Pharmacists sometimes measure medicines in the unit of "grains," where 1 gr = 65 mg. The label on a bottle of aspirin reads "Asp

viva [34]

Answer:

325mg of Aspririn

Explanation:

First you should note the information that the problem gives you:

- The bottle of Aspirin has 5gr (grains)

- 1gr(grain) = 65mg (miligrams)

Also, the problem is asking about how many aspirin are in 5 gr (grains), so you should use a conversion factor, as follows:

-First you should put the quantity you need to convert:

$5grAspirin$

-Then you write the denominator of the conversion factor that must have the same units that you want to convert, in this case gr:

$5grAspirin*\frac{}{1grAspirin}$

-Then you write the numerator with the units that you want to obtain and the numerical equivalence between the units, in this case:

$5grAspirin*\frac{65mgAspririn}{1grAspirin}$

-Finally you multiply numerators and divide by denominators:

$5grAspirin*\frac{65mgAspririn}{1grAspirin}=325mgAspririn$
