Explanation:

Given parameters:

Distance of star from earth  = 36 trillion miles

Unknown:

Distance in light years  = ?

Solution:

A light year is the distance light travels in one year.

  1 mile  = 1.7 x 10⁻¹³ light years

 36 trillion miles  = 36 x 10¹² x 1.7 x 10⁻¹³ light years

in antacid tablets neutralizes hydrochloric acid in the stomach. A tablet containing 0.25 g of
aluminum hydroxide is ingested by a patient with 0.88 g of hydrochloric acid in their stomach. Is
this tablet sufficient to neutralize the acid in the patient's stomach? Explain using stoichiometric
calculations. [4 marks]
I

Answers

This tablet insufficient to neutralize the acid in the patient's stomach

Further explanation

Reaction

Al(OH)₃(s) + 3HCl(aq) ⇒ 3 H₂O(l) + AlCl₃(aq)

0.25 g of  Aluminum hydroxide-Al(OH)₃ , mol (MW=78 g/mol) :

[tex]\tt \dfrac{0.25}{78}=0.00321[/tex]

mol HCl : mol Al(OH)₃ = 3 : 1

[tex]\tt mol~HCl=3\times 0.00321=0.00963[/tex]

mass HCl (MW=36,46 g/mol) :

[tex]\tt 0.00963\times 36.46=0.351[/tex]

0.351 < 0.88⇒this tablet insufficient to neutralize the acid

If the reacants of a chemical raction have 15 Carbon atoms, 72 Lead
atoms, and 88 Nitrogen atoms, what will the products have?

Answers

Answer:

In the human body, potential energy is stored in the bonds between atoms and molecules. Chemical energy is the form of potential energy in which energy is stored in chemical bonds. When those bonds are formed, chemical energy is invested, and when they break, chemical energy is released. Notice that chemical energy, like all energy, is neither created nor destroyed; rather, it is converted from one form to another. When you eat an energy bar before heading out the door for a hike, the honey, nuts, and other foods the bar contains are broken down and rearranged by your body into molecules that your muscle cells convert to kinetic energy.

10. The molar mass of CS2 is 76.14 g/mol. How many grams of CS2 are present in 10.00 mol?

Answers

Answer: C

Explanation:

There are 761.4 grams of CS2 in 10.00 mol.

To calculate the amount of grams present in a given amount of moles, the molar mass of the substance must be used, as follows:

                                        [tex]m = MM \times mol[/tex]

In this way, just perform the following operation:

                           

                                          [tex]m = 76.14 \times 10[/tex]

                                         [tex]m = 761.4 grams[/tex]

Thus, there are 761.4 grams of CS2 in 10 mol of the substance.

Which of the following is a difference between naming ionic and covalent compounds?
Group of answer choices

In ionic compounds the ending of the second element changes to -ide, but not in covalent compounds.

In covalent compounds, the prefix of the first element is always ignored but the prefix in the second element depends on the subscript of the element. In ionic compounds, the subscript on each element does not affect the name of the compound.

In covalent compounds the ending of the second element changes to -ide, but not in ionic compounds.

In covalent compounds, the prefix of the first element and second element depends on the subscript of each element. In ionic compounds, the subscript on each element does not affect the name of the compound.

Answers

An ion with fewer electrons than its neutral atom is called a(n) cation. The charge of an ion with more electrons than its neutral atom is. negative.

The difference between naming ionic and covalent compounds is that, in ionic compounds the ending of the second element changes to -ide, but not in covalent compounds.

Ionic compounds are compounds that are formed by the by the transfer of electrons from a metal to a nonmetal. Covalent compounds are formed when electrons are shared between nonmetals.

For ionic compounds, the name of the second element(the nonmetal) often ends in -ide. For instance; sodium bromide, cesium oxide and potassium nitride. This does not apply when naming covalent compounds. The are named based on the subscripts of each element in the compound.

When a hammer strikes a nail, the nail

Answers

Answer:

The nail will exert a force of equal strength in the opposite direction on the first object.

Explanation:

"According to Newton's third law of motion, when a hammer strikes and exerts force on a nail, the nail exerts a force of equal strength in the opposite direction on the first object."

Basically, if you push someone, they will fall over right?

Still, you will feel the force as you push them over, and you might stumble back while they are pinwheeling and falling into a pool.

That force is that torque when the person's weight is also pushing back at you while your force is pushing at them.

what happens to the temperatures when we have direct sunlight vs indirect sunlight?

Answers

Explanation:

When we have direct sunlight, the temperature is higher compared to indirect sunlight.

Direct sunlight is usually overhead whereas indirect sunlight is at an angle to the surface.

Direct sunlight impacts the surface with more energy concentrated on a smaller surface area. This warms the surface more. Indirect sunlight is diffuse and spreads over a wider area. This leads to a reduction in temperature.
