Chemistry
1 answer:
laiz [17]3 years ago
8 0

Answer:

Explanation:

8.97 x 10⁵ \frac{m}{s^2}

= 8.97 x 10² x 10⁵ \frac{cm}{s^2}

= 8.97 x 10² x 10⁵cm /(10³ms)²

= 8.97 x10 x 10⁶cm / 10⁶ ms²

= .897 x 10² \frac{cm}{ms^2}

10. Which of the following mirror is used to form smaller image
vitfil [10]

Answer:

Correct answer is b) convex mirror

Explanation:

A convex mirror, which bulges outward, reflects at a wider angle near its edges than at its center, creating a slightly distorted image that's smaller than actual size. Convex mirrors have many uses. The smaller size of the images means that you can see more with these surfaces, hence their use in safety mirrors.

If a gas has a volume of 350 mL at 780 mm Hg, what pressure will be needed to cause its volume
makkiz [27]

The required pressure of the gas is 546 mmHg.

<h3>What is the relation between volume and pressure?</h3>

Relation between the volume and pressure of gas is explained through the ideal gas equation PV = nRT, and for the question required equation is:

P₁V₁ = P₂V₂, where

P₁ & V₁ are the initial pressure and volume.

P₂ & V₂ are the final pressure and volume.

On putting values from the question to the equation, we get

P₂ = (780)(350) / (500) =

P₂ = 546 mmHg

Hence required pressure is 546 mmHg.

If atoms are not destroyed, what happens to them
Snowcat [4.5K]

The 1st law of thermodynamics doesn't  specify that matter can be created nor destroyed, but that the total amount of energy in a closed system cannot be created nor destroyed though it can be changed from one form to another.

Arrange the following molecules by increasing bond polarity...?
Radda [10]

The correct answer is Cl₂ <CCl₄ < PCl₃ < CaCl₂ < CsCl (most polar)

Cl₂ is nonpolar or least polar as there is no differentiation in electronegativity of the two atoms of chlorine producing amongst them. CCl₄ exhibits four C-Cl bonds. The C-atom is electropositive and Cl is electronegative. Therefore, there are four dipoles in CCl₄. Though, these dipoles cancel each other because of the tetrahedral geometry of the molecule. Therefore, CCl₄ is less polar in comparison to others, however, more polar in comparison to Cl₂.  

PCl₃ exhibits three dipoles because of electronegative chlorine atoms, and electropositive phosphorus atom. Though, the configuration of the molecule is trigonal pyramidal, producing it more polar in comparison to CCl₄. The CaCl₂ is ionic compound, therefore, polar in comparison to the covalent bond compounds.  

CsCl is ionic compound, however, more polar in comparison to CaCl₂, as there is the higher difference in electronegativity of Cs and Cl compared with that between the Ca and Cl.
