Answer:
Molarity = 3.625 M
Explanation:
Given data:
Mass of HCl = 53.0 g
Volume of water = 400.0 mL (400/1000 = 0.4 L)
Molarity of solution = ?
Solution:
Number of moles of of HCl:
Number of moles = mass/ molar mass
Number of moles = 53 g/ 36.5 g/mol
Number of moles =1.45 mol
Molarity:
Molarity = number of moles of solute / volume of solution in L
Molarity = 1.45 mol / 0.4L
Molarity = 3.625 M
Answer is: <span>a hill over which a wagon is pushed.
</span>For all chemical

and exothermic reaction (chemical reaction that releases more energy than
it absorbs).

Answer:
Agree this is correct if it not blame me
Answer:
Explanation:
Glucose reacts with oxygen do produce carbon dioxide and water:
Given a daily mass of glucose:
Find moles of glucose:
From stoichiometry of this equation, moles of carbon dioxide can be found by multiplying this amount by 6:
Convert this into mass using the molar mass of carbon dioxide:
This is the mass of carbon dioxide per person per day. Multiply by the population and by the number of days to get the total mass:
Answer:
a rapidly flowing river discharges into the ocean where tidal currents are weak.
Explanation:
The force of the river pushing fresh water out to sea rather than tidal currents transporting seawater upstream determines the water circulation in these estuaries.
