It's football season! Big Bubba Brown is running full speed trying to tackle the quarterback before he throws the ball. Wham! He got him! What happens to Big Bubba Brown?
A. Bubba uses all of his energy to tackle the quarterback.
B. Bubba and the quarterback lose their energy and fall to the ground.
C. Some of Bubba's energy is transferred to the quarterback and Bubba slows down.
D. Bubba knocks the quarterback down and keeps running at the same speed as before the tackle.

this is science btw.

The carbon and silicon have in common that they belong to the same column (family), therefore they have the same number of total electrons. So, option B is correct.

Carbon's closest analogue is silicon. Silicon and carbon are both tetravalent atoms that primarily form covalent (non-ionic) compounds. However, aside from the fact that both elements "can form four covalent bonds," there is surprisingly little in common between them.

Carbon has an atomic number of 6 and an electronic configuration of 2, 4. Silicon has an atomic number of 14 and an electronic configuration of 2, 8, 4. Because both elements have the same number of valence electrons, they are classified as being in the same group.

Thus, option B is correct.

Answer:

The equation for percent composition is (mass of element/molecular mass) x 100.

please mark me as a brainlist

Explanation:

A mining crew extracted two different types of minerals from underground. Then, they transferred the same amount of energy into both minerals. Mineral A changed and mineral B stayed the same phase because mineral B has a stronger molecular attraction than mineral A.

Answer:

Excess reactant - Reactant that can produce more of the product

Limiting reactant - Reactant that can produce a lesser amount of the product

Theoretical yield - Amount of product predicted to be produced by the given reactants

Explanation:

In every chemical reaction, there is a limiting reactant and there is an excess reactant.

The limiting reactant determines the amount of product obtained. It is the reactant that produces a lesser amount of the product.

The excess reactant is known to be the reactant that produces a greater amount of the product.

The theoretical yield is calculated using the limiting reactant and is the amount of product predicted to be produced by the given reactants.

Answer:

43.76 g = 0.04376 Kg

Explanation:

The equation of the reaction is given as;

H2 + Cl2 --> 2HCl

From the equation;

1 mol of Cl2 produces 2 mol of HCl

Converting to mass;

Mass = Number of mol * Molar mass

Cl2;

Mass = 1 mol * 70.906 g/mol = 70.906 g

HCl;

Mass = 2 mol * 36.458 g/mol = 72.916 g

This means;

70.906 g of Cl2 produces 72.916 g of HCl

x g of Cl2 would produce 45g of HCl

70.906 = 72.916

x = 45

x = 45 * 70.906 / 72.916

x = 43.76g

Answer:

Atom, cell, dust particle, ant, ping pong ball

Explanation:

Firstly, atoms make up all matter, including each of the items on that list. The only things smaller than atoms are the parts of the atom itself, protons, neutrons and electrons. Because none of those are on that list, atoms have to be the smallest. Next smallest is the cell. Cells are made up of atoms, but they also in part make up dust. You can see a dust particle with the naked eye, but in order to see a cell you must use a microscope. Thus, cells are smaller than dust particles. Next is an ant. Obviously, an ant is bigger than a speck of dust, and is made up of cells and atoms. Lastly all you have is the ping pong ball, which is much larger than the rest of the items. Hope this helps!

All matter, including each thing on the list, is made up of atoms. The protons, neutrons, and electrons that make up an atom are the only particles smaller than atoms.

Thus,  Atoms must be the tiniest object because none of those are included in that list. The cell is the next smallest. Atoms make up cells, but dust also makes up a portion of them.

A dust particle can be seen with the unaided eye, but a microscope is required to see a cell.

Cells are hence smaller than dust particles. An ant comes next. Of course, an ant is composed of cells and atoms and is larger than a particle of dust.

Thus, All matter, including each thing on the list, is made up of atoms. The protons, neutrons, and electrons that make up an atom are the only particles smaller than atoms.

Answer:

7.28 mol Na2SO4

Explanation:

Since it is already in moles, all we have to do is use a molar ratio

A molar ratio is the proportions of reactants and products using the balanced equation. When writing a mole ratio, the given information must cross out with the right thing.

7.28 mol H2SO4 * 1 mol Na2SO4/1 H2SO4 = 7.28 mol Na2SO4

Answer:

0.67atm is the new pressure of the gas

Explanation:

To find one condition of a gas when pressure, volume and absolute temperature change we must use combined gas law:

[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]

Where P is pressure, V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.

Replacing:

P₁ = 1.12atm

V₁ = 156mL

T₁ = 28.1°C + 273.15K = 301.25K

P₂ = ?

V₂ = 312mL

T₂ = 87.2°C + 273.15 = 360.35K

1.12atm*156mL / 301.25K = P₂*312mL / 360.35K

P₂ = 0.67atm is the new pressure of the gas

Answer:

0.316 moles are produced.

Explanation:

We state the redox reaction:

4HNO₃   + Cu   →  Cu(NO₃)₂ + 2NO₂ + 2H₂O

We need to determine the limting reactant:

0.1 L . 14 M = 1.4 moles

10 g . 1mol/ 63.54g =0.158 mol

Cu is the limiting reactant. Let's see

4 moles of acid need 1 mol of Cu to react

1.4 moles of acid may react to (4 . 1) / 1.4 = 0.35 moles

We do not have enough Cu.

1 mol of Cu can produce 1 mol of NO₂

Then 0.158 moles will produce, 0.316 moles. (double of moles)

If we see stoichiometry, ratio is 1:2

Answer:

When the solar winds approach the Earth, the magnetosphere (part of the Earth's natural magnetic defenses) deflects/repels most of the charged particles and shields our planet's surface from the winds. Sometimes, however, the magnetosphere isn't strong enough to block the Earth from these winds, so they do hit Earth and may cause catastrophic consequences, such as ruin power grids, cut off telecommunications (cell service/calls), etc.
