Water would have a much lower boiling point much like its other hydrides and it would loss its ability to dissolve polar substances plus it couldn't form water columns so no more cohesion between water molecules
2 boxes of A
Because C = A + B
2 of A = 20 grams
at the other hand we have 2 of B = 10
So 20 + 10 = 30 grams
Answer:
Q = 96.6 j
Explanation:
Given data:
Heat required = ?
Initial temperature = 19°C
Final temperature = 33°C
Mass of disc = 3.0 g
Specific heat capacity = 2.3 J/g.°C
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 33°C - 19°C
ΔT = 14°C
Q = 3.0 g×2.3 J/g.°C × 14°C
Q = 96.6 j
0.1 moles of chloride ions were involved in the reaction if 25.0 mL of a 2.00 M CaCl2 solution is used for the reaction.
Explanation:
Data given:
volume of Ca
= 25 ml 0r 0.025
molarity of the calcium chloride solution = 2M
number of chloride ions =?
Balance chemical reaction:
Ca + 2 ⇒
number of moles in 25 ml is calculated as:
molarity = 
number of moles of calcium chloride = molarity x volume
putting the values in the equation:
number of moles = 2 x 0.025
= 0.05 moles of calcium chloride
1 mole of Ca decomposes as 1 calcium ion and 2 chloride ions
so 0.05 moles will have x moles of chloride ion
= 
x= 0.1
0.1 moles of chloride ions will be involved in the reaction.
Asteroids are rocky space debris that are formed from interspacial collisions and collection of dusty particles. our solar system has an enormous asteroid belt between Mars and Jupiter.
Jupiter also has more local asteroids that are locked to its gravitational pull.
Not to be confused with a comet or meteor.
