A mixture that results when substances dissolve to form a homogeneous mixture is a solution.
Answer:
Cl2 + 2NaBr --> 2NaCl + Br2
Explanation:
This is a single displacement reaction where one side of the ionic compound switches with the other.
So, Cl2 + NaBr ---> NaCl + Br2
This isolates the Bromine and puts the Chlorine in it's place.
Then, balance out the equation like so and you should get
Cl2 + 2NaBr --> 2NaCl + Br2
Answer:
10 km/hr
Explanation:
We are told that a jogger runs;
3km in 0.3 hr and
7 km in 0.7 hr
We are required to determine the average speed;
We need to know that average speed is given by;
Average speed = Total distance ÷ total time
In this case;
Total distance = 10 km ( 3km + 7 km)
Total time = 0.3 hr + 0.7 hr
= 1 hr
Thus;
Average speed = 10 km ÷ 1 hr
= 10 km/hr
Therefore, the average speed of the jogger is 10 km/hr
Answer:
The answer is option C.
Explanation:
A covalent bonded molecule when not dissolved in an aqueous solution does not contain any ions hence does not conduct electricity making it an insulator.

Explanation:
Your exercise: Step by step:
1*225/88*r*a=1*(0/-1)*e+1*(__/88)*r*a | If the numerator equals zero, the fraction will be zero
1*225/88*a*r=1*0*e+1*(__/88)*r*a | Multiply 0 by e. Any number multiplied by 0 is 0.
1*225/88*a*r=0+1*__/88*r*a | Multiply __/88 by a. You can multiply a fraction by a number by multiplying the number and the numerator.
1*225/88*a*r=0+1*__*a*a*r | Multiply (__*a)/88 by r. You can multiply a fraction by a number by multiplying the number and the numerator.
1*225/88*a*r=0+1*(__*a*r)/88 | · 88
1*225*a*r=88*(__*a*r)/88 | Multiply 88 by (__*a*r)/88. You can multiply a fraction by a number by multiplying the number and the numerator.
225*a*r=88*(__*a*r)/88 | Cancel (__*88*a*r)/88 with 11*2^3
225*a*r=(__*a*r)/1 | Numerator 1 of (__*a*r)/1 can be omitted .
225*a*r=1*__*a*r | : 225
1*a*r=1*__*0.004*a*r | Divide both sides by a .
1*r=1*(__*0.004*a*r)/a
