CaCl2(aq) + 2AgNO3(aq)) → Ca(NO3)2(aq) + 2AgCl(s)

Answers

Answer 1
Answer:

Word Equation: Calcium chloride + Silver nitrate → Calcium nitrate + Silver chloride (precipitate).

Type of Reaction: Double displacement (precipitation).

The chemical equation can be converted into a word equation as follows:

Word Equation:

Calcium chloride (aqueous) + Silver nitrate (aqueous) → Calcium nitrate (aqueous) + Silver chloride (solid)

Type of Reaction:

This is a double displacement reaction, specifically a precipitation reaction. In a double displacement reaction, the cations and anions of two compounds switch places, resulting in the formation of two new compounds. In this particular case, when calcium chloride and silver nitrate are mixed, calcium nitrate and silver chloride are formed.

Furthermore, it's a precipitation reaction because one of the products, silver chloride, is insoluble in water and forms a solid (precipitate) rather than remaining in solution. The solid silver chloride is observed as a white, cloudy precipitate that settles at the bottom of the reaction vessel.

The question probable may be;

CaCl2(aq) + 2AgNO3(aq)) → Ca(NO3)2(aq) + 2AgCl(s)

Convert this into word equation and tell what type of reaction is this?

Answer 2
Answer: CaCl₂ + 2 AgNO₃ = Ca(NO₃)₂ + 2AgCl

Calcium Chloride + Silver Nitrate = Calcium Nitrate + Silver Chloride

A body of mass 5kg has momentum of 125kgm/s. find the velocity of the body in motion.

Answers

Explanation:We have momemtum = mass X velocity

    p = mv

    OR, p/m = v

    v = (125kg m/s)25kg

    v = 125/25 m/s

       v = 5 m/s

A gas is initially at a pressure of 225 kPa and a temperature of 245 K in a container that is 4.5 L. If the gas is compressed to a volume of 2.1 L and the temperature changes to 275 K, what is the new pressure?

Answers

Use the ideal gas equation PV=nRT. You can compare before and after using P1V1/n1T1=P2V2/n2T2. Since the number of moles remains constant you can disregard moles from the equation and use pressure, volume and temp. Make sure your pressure is converted to atmospheres, your volume is in liters, and your temperature is in kelvins.

A 1.00 L volume of HCl reacted completely with 2.00 L of 1.50 M Ca(OH)2 according to the balanced chemical equation below. 2HCl + Ca(OH)2 > CaCl2 + 2H2O What was the molarity of the HCl solution?it is either 6.00 M or 0.375 M

Answers

The first step is to find the number of moles of OH⁻ that reacted with the HCl.  To do this multiply 2.00L by 1.50M to get 3 moles of Ca(OH)₂.  Then you multiply 3 by 2 (there are 2 moles of OH⁻ per every 1 mole of Ca(OH)₂) to get 6 moles of OH⁻.  That means that you needed 6 moles of HCl since 1 mole of HCl contains 1 mole of H⁺ and equal amounts H⁺ and OH⁻ reacted with each other.  To find the molarity of the HCl solution you need to divide 6mol by 1L to get 6M.  Tat means that the concentration of the acid was 6M.

I hope this helps.  Let me know if anything was unclear.

Which change in oxidation number indicates oxidation?(1) –1 to +2 (3) +2 to –3
(2) –1 to –2 (4) +3 to +2

Answers

The change that shows an oxidation is the change  –1 to +2.

What is oxidation?

The term oxidation has to do with an increase in oxidation number. This increase will always be positive.

Hence, we have to look out for the change in which there is an increase in oxidation number and this occurs for the change –1 to +2.

(giving away 10 points)at what position of the earth in its orbit is it summertime in the northern hemisphere
Position 2
position1
position4
position3

Answers

Answer: Position 1

Explanation:

Seasons on Earth occur due to tilt of of its axis. Earth's axis is tilted 23.5° from horizontal. Thus, when Earth moves in the orbit around sun, sometimes the northern hemisphere points towards the Sun and sometimes away. When it points towards the Sun, it experiences Summer season and while it points away, winter occurs. In between, spring and autumn occur.

Thus, from the given diagram, norther hemisphere would have summer time at position 1 when the northern hemisphere is facing the Sun.

Answer:

The correct answer is Position 1.

Explanation:

The rotational motion of the Earth causes some parts to receive more heat from the sun, while others receive less. Its axis of rotation runs vertically from the North Pole to the South Pole. Since this axis is not completely vertical, the sun's rays are projected with different intensity during the translation movement. Since the Earth is tilted slightly to the left and the axis points to the side where the Sun is at position 1, the sun's rays reach the northern hemisphere with more intensity and the southern hemisphere with less intensity.
