Answer:
<u>addition</u>
Explanation:
because you add the two chlorides by breaking the carbon carbon double bond
Answer:
Explanation:
How many atoms are in a 3.5 g sample of sodium (Na)? In this example, multiply the grams of Na by the conversion factor 1 mol Na/ 22.98 g Na, with 22.98g being the molar mass of one mole of Na, which then allows cancelation of grams, leaving moles of Na.
Answer : The final temperature of the system is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of gold =
Note : Molar heat capacity of gold =
Heat capacity of gold =
= heat capacity of water =
= mass of gold = 13.00 g
= mass of water = 13.00 g
= final temperature of system = ?
= initial temperature of gold =
= initial temperature of water =
Now put all the given values in the above formula, we get:
Therefore, the final temperature of the system is,
An oxygen molecule at 25◦C has a speed of 1520 miles/hour.
<h3>Equation :</h3>
As we know
1 km = 1000 meter
So,
678 / 1000 = 0.678 km
And 1 mile = 1.6 km
So,
0.678 / 1.609 = 0.4213 miles
We know that 1 hour = 60×60 = 3600 sec
So,
1 sec = 1 / 3600
= 2.777 x 10⁻⁴ hour
Now finding speed,
speed = distance / time
speed = 0.4213 / 2.777 x 10⁻⁴
speed = 1520 miles/hour
<h3>What is speed ?</h3>
Velocity is the rate and direction of an object's movement, whereas speed is the time rate at which an object is moving along a path. In other words velocity is a vector value, whereas speed is a scalar value.
