Explanation:

If two compounds chemically react together and upon interchanging their elements with each other is known as a double displacement reaction.

For example, $Ca(OH)_{2} + 2HCl \rightarrow CaCl_{2} + 2H_{2}O$

In this reaction, OH in $Ca(OH)_{2}$ is replaced by Cl of HCl. As a result, $CaCl_{2}$ is formed.

Therefore, the statement when calcium hydroxide powder is placed into a hydrochloric acid solution, aqueous calcium chloride and water are formed, is true.

Answer: yes, when calcium hydroxide powder is placed into a hydrochloric acid solution, aqueous calcium hydroxide and water are formed.


Explanation:

1) Calcium hydroxide is a base whose chemical formula is: Ca(OH)₂

2) Hydrochloric acid is the acid with chemical formula HCl

3) Acids and bases react in a double replacement reaction forming salt plus water: Acid + Base → salt + water


4) The specific chemical equation for these reactants is:

Ca(OH)₂ (s) + 2HCl(aq) → CaCl₂ (aq) + 2H₂O(l)

5) CaCl₂ is calcium chloride, a salt, and H₂O is water

A sample of seawater has 0.075 g of sodium chloride per mL of solution. How many moles of sodium chloride are there per liter of

amm1812

Answer:

1.28 mol

Explanation:

mole = mass/molar mass

n = v/v/cm³

mass = 0. 075g

v = 1dm³ =1000cm³

n= m/MV=0.075/58.44(1000)

n =1.28 mol

How are fluids used and controlled in manufactured devices?

BlackZzzverrR [31]

Answer:

Fluid power systems perform work by a pressurized fluid bearing directly on a piston in a cylinder or in a fluid motor. A fluid cylinder produces a force resulting in linear motion, whereas a fluid motor produces torque resulting in rotary motion. Within a fluid power system, cylinders and motors (also called actuators) do the desired work. Control components such as valves regulate the system.

Answer: similar, energy

Explanation: (edmentum answer) Several of the elements in period 5 have electron configurations with only one electron in the 5s sublevel. That suggests that the next sublevel that electrons typically fill, 4d, is not much higher in energy.

In cucumbers, green skin (G) is dominant to striped skin (g). If a farmer crosses a heterozygous (hybrid) cucumber with a homozy

Elena L [17]

Answer:

Half will be green and half will be striped

Explanation:

Given green skin (G) is dominant to striped skin (g).

Cucumber 1 : Heterozygous (Gg)

Cucumber 2 : Homozygous striped (gg)

When Gg X gg :

G g

g Gg gg

Half of the offspring will have Gg genotype so they will be green. Other half will have gg genotype so they will be striped.
