Answer:
Newton's First Law of Motion
Explanation:
Newton’s first law of motion is when an object can’t move or change their speed without some type of force. Inertia is included since is caused by unbalanced force.
Explanation:
We will balance equation which describes the reaction between sulfuric acid and sodium bicarbonate: as follows.
Next we will calculate how many moles of are present in 85.00 mL of 1.500 M sulfuric acid.
As, Molarity =
1.500 M =
n = 0.1275 mol
Now set up and solve a stoichiometric conversion from moles of to grams of . As, the molar mass of is 84.01 g/mol.
= 21.42 g
So unfortunately, 15.00 grams of sodium bicarbonate will "not" be sufficient to completely neutralize the acid. You would need an additional 6.42 grams to complete the task.
Answer:
Some of the properties of cobalt silicate include:
It occurs as a crystal with red- violet type colour.
The shape of the cobalt silicate crystal is orthorhombic.
The molecular weight of cobalt silicate is 209.95.
The melting temperature of Cobalt Silicate is 1618 degrees Celsius.
The density of Cobalt Silicate is 4.63 grams per centimetre cube.
Cobalt Silicate can serve as a semi-conductor.
Answer:
The answer to your question is E = 419.435 J
Explanation:
Data
Mass = m = 2.004 g
Temperature 1 = T1 = 89°C
Temperature 2 = T2 = 139°C
Specific heat of water = Cp = 4.186 J/g°C
Energy = E = ?
Formula
E = mCp(T2 - T1)
Substitution
E = (2.004)(4.186)(139 - 89)
Simplification and result
E = 8.3887(50)
E = 419.435 J
