PLEASE HELP!!!A student mixed two clear liquids together in a beaker and a solid precipitate formed. His data is shown below:
Liquid reactant A: 10 g
Liquid reactant B: 17 g
Beaker+Solid product: 32 g

What is the mass of the beaker?
a. 5 g
b. 10 g
c. 15 g
d. 17 g
e. 32 g

Answers

Answer 1

Answer:

This might be right. Im not quite sure. This is what my 5th grade science teacher told me. 'Look at the 2 LR's and add them together. Then look at the total amount which is 32. When you add the 2 LR's you get 17. So subtract 17 from 32 and you get 15. So: C:15 is your answer." (LR's stands for liquid reactants)

10+17=17

Total amount is 32

32-17=15

15 is you mass

Hope this Helps

Speed in a given direction is called what?

Answers

Speed in a given direction is called velocity. Velocity describes the speed and direction of an object's motion.

The speed and direction of an object's motion are described by velocity, a fundamental notion in physics. It is a vector quantity, which means it contains magnitude as well as direction. While speed just refers to how quickly an object moves, velocity includes the concept of direction, providing a more full description of the object's motion.

One key feature of velocity is that it can alter depending on whether the speed or direction of motion changes. The velocity of an object, for example, remains constant if it moves in a straight line at a constant speed. However, if the object's speed or direction changes, the velocity changes as well.

Speed is a scalar measure, and only has magnitude
If you add a direction to it you are making it a vector.

What is the order of steps through which a particle of gaseous water would travel as it made one complete trip through the water cycle

Answers

The order of steps through which a particle of gaseous water would travel as it made one complete trip through the water cycle are Evaporation, Condensation, Precipitation, Runoff, Infiltration, and Transpiration.

What are the sequential stages of the water cycle?

Water cycle refers to the continuous process of water movement on Earth involving evaporation, condensation, precipitation, and more. The water cycle, also known as the hydrologic cycle, consists of several interconnected stages.

It begins with evaporation, where water from bodies of water and the Earth's surface turns into water vapor due to heat from the sun. This vapor then undergoes condensation, forming clouds.

Precipitation occurs when condensed water droplets combine and fall as rain, snow, sleet, or hail. Surface runoff carries excess water to larger bodies, while infiltration sees water seep into the ground. Transpiration involves plants releasing water vapor into the atmosphere. These processes together complete the cycle.

Answer:

[H+] is decreased.

Explanation:

Arrhenius Theory:

An acid is a substance which produces one or more hydrogen ions, (H+) in aqueous solution.

Examples:

$HCl(aq)>H^+(aq)+Cl^-(aq)\n\nHBr(aq)>H^+(aq)+Br^- (aq)\n\nH_2 SO_4(aq)>2H^+(aq)+SO_4^2- (aq)\n\nH_3 PO_4(aq) >3H^+ (aq)+PO_4^3-(aq)\n\nCH_3 COOH(aq)>CH_3 COO^- (aq)+H^+ (aq)$

A Base is a substance which produces one or more hydroxyl ion or hydroxide ion (OH-) in aqueous solution.

Examples

$NaOH(s)>Na^+ (aq) + OH^- (aq)\n\nKOH(s)>K^+ (aq) +OH^- (aq)\n\nCa(OH)_2 (s)>Ca^(2+) (aq)+2OH^-(aq)\n\nAl(OH)_3 (s)> Al^(3+)(aq)+ 3OH^- (aq)$

Please note:

(aq) stands for aqueous which means in the presence of water that is, water acts as a solvent

So, on adding a base to the water increase in $[OH^-]$ will take place and this will decrease the Hydrogen ion concentration

Pure water contains $[H^+]=[OH^-]$

if the solution is acidic $[H^+ ]>[OH^- ]$

if the solution is Basic $[H^+ ]<[OH^- ]$

Answer:

Explanation:

The first and most obvious statement is that [OH-] is increased, but that is not offered to you.

The second most obvious statement is that the [H+] ion is decreased. That is offered to you. It is C

Carbon burns with oxygen to produce carbon dioxide gas. Which of these shows the correct chemical reaction?A) CO2 = C + O
B) C + O = CO2
C) C+ O -> CO2
D) C, O, CO2

Answers

The correct option is C.

When writing chemical equations, the chemical symbols of the element are usually used together with numbers to indicate the ratio of each element in the chemical compounds. The additional sign is usually used in between the reactants and the products. The arrow sign in used to show the direction in which the reaction is proceeding. In the correct option given above, the arrow sign is used to indicate that the reaction is moving in the forward direction.

Answer:

C) C+ O -> CO2

Select the correct answer.If a silver nitrate solution is added to excess sodium sulfide, this reaction takes place: 2AgNO3(aq) + Na2S(aq) → Ag2S(s) + 2NaNO3(aq).
Suppose you use 0.0150 liter of a 2.50 M solution of silver nitrate. Assuming the reaction goes to completion, how much silver sulfide is produced? Use the periodic table.
A. 1.49 g
B. 4.65 g
C. 9.30 g
D. 18.6 g

Answers

Answer:- B. 4.65 g.

Solution:- The given balanced equation is:

$2AgNO_3(aq)+Na_2S(aq)\rightarrow Ag_2S(s)+2NaNO_3(aq)$

It asks to calculate the mass of silver sulfide formed by when 0.0150 liters of 2.50 M of silver nitrate are used.

Moles of silver nitrate are calculated on multiplying it's liters by its molarity and then on multiplying by mol ratio, the moles of silver sulfide are calculated. These moles are multiplied by the molar mass to convert to the grams.

Molar mass of $Ag_2S$ = 2(107.87)+32.06 = 247.8 g per mol
