A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions .

It is a homogeneous mixture since the components of tap water are blended so that it looks like a single substance, since you only see water and nothing else.

(Heterogenous mixtures are mixtures in which the separate components that make up the substance are visible .)

It is homogeneous too ...

Answer:

1. A mixture is a material made up of two or more different substances which are physically combined.A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspension and colloids.

2. Tap water is a homogeneous mixture, not heterogeneous. This is because tap water has dissolved minerals inside it, but they are equally distributed throughout the water.

3. 70% rubbing alcohol means that 70% of the molecules in the rubbing alcohol is actually alcohol. The other 30% is water. As I have stated at the start the answer, although alcohol is technically pure, rubbing alcohol is not purely made of alcohol.

For the reaction co(g)+2h2(g)<->ch3oh(g) at 700. k, equilibrium concentrations are [h2] = 0.072 m, [co] = 0.020 m, and [ch
SVETLANKA909090 [29]
The balanced equation for the reaction is
CO(g) + 2H₂(g) ⇄ CH₃<span>OH(g)

Since given concentrations are at equilibrium state, the expression for the equilibrium constant, k can be written as
   k = [</span>CH₃OH(g)] / [CO(g)] [H₂(g) ]²

By substitution,
   k = 0.030 M / 0.020 M x (<span>0.072 M</span>)²
   k = 289.35 M⁻²

a faucet is leaking water at a speed of 5 drops per minute. If 1 ml is equivalent to 10 drops, how many liters of water will be
nikdorinn [45]

Answer: 0.72 litres of water is wasted in one day.

Explanation:

First you need to find out how many minutes are in a day. Do this by multiplying the number of minutes in an hour (60) by the number of hours in a day (24). 24 x 60 = 1440. If the faucet is dripping at 5 drops per minute, then multiply 5 by the number of minutes in a day (1440) to see how many drops drip in one day. 5 x 1440 = 7200. Now we need to figure out how many mL fo water that is. if 10 drops is 1 mL, then we need to divide the total number of drops (7200) by 10. 7200 divided by 10 is 720. That means 720 mL of water is dripping per day. Finally, we must convert mL to litres. There are 1000 mL in one litre, so divide 720 by 1000. The final answer is 0.72
