Answer:
3.3 hours
Explanation:
Given data:
Speed of coach = 90 km/h
Distance to be covered = 300 km
Time taken = ?
Solution:
Formula:
v = d/ t
v = speed
d = distance
t = time
Now we will put the values in formula,
v = d/ t
t = d/ v
t = 300 km / 90 km/h
t = 3. 3 h
Answer:
3.2 Calories
Explanation:
Here we will use a formula
Heat added in calories = Mass of glass x Increase in temperature x specific heat of glass
As we know that, specific heat is the amount of energy required to raise the temperature of one gram of any substance by 1°C. It has a constant value for every substance and for glass the specific heat is .16 calories/gm
Incorporating the values of mass (m), temperature(T) and specific heat (c) in formula.
calories (small calories) = l.0 g x 20 degrees x .16 calories/gm/°C
= 3.2 calories

Answer:
Explanation:
Hello,
In this case, since the given undergoing chemical reaction is correctly balanced, the reaction quotient is computed as well as the equilibrium constant but in terms of the given concentrations that are:
In such a way, the reaction quotient turns out:
Taking into account that carbon is not included since it is solid.
Best regards.
Baking soda. to put in the most simple terms..
-OH is the "base" anion
H+ is the "acid" ion
Answer:basically anything you can taste, smell, or hold consists of matter and is therefore a chemical.
