Answer:
Mud was deposited first, then sand.
Explanation:
This could have been a tidal mud flat succeeded by a sandy beach, or along the bed and course of a river with either mountain building upstream causing faster flow and carrying of mud farther away or the sea level falling with mud deposits being found closer to the new coastline. Hope this helps!
Answer:
<h3>The answer is 4 N</h3>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 2 × 2
We have the final answer as
<h3>4 N</h3>
Hope this helps you
Answer:
Total 5 significant digits.
Explanation:
Significant digits are the numbers that give a meaningful contribution. For example, digit 013 has the 2 significant digits and zero is not a significant digit because digits 1 and 3 give meaningful contribution but digit zero does not value meaningful contribution. Similarly, the 89015 has a total of 5 significant digits and these digits are the 8, 9, 0, 1, and 5.
Answer:
1. 2.17 dm^3
2. 109.1 dm^3
3. 0.398 atm
Explanation:
1. Considering the equation of the reaction;
Number of moles of chlorine gas in 3.44 g= 3.44/2(35.5)= 0.0485 moles
Since we can see from the equation that
1 mole of chlorine gas yields 2(22.4) dm^3 of HCl
0.0485 moles of chlorine gas yields 0.0485 moles × 2(22.4)dm^3/1= 2.17 dm^3
2. Note that 1 mole of Kr occupies 22.4 dm^3
Therefore 4.87 moles of Kr will occupy 4.87 × 22.4 dm^3/1 = 109.1 dm^3
3. From PV= nRT
n= 0.0485 moles
V= 4.55 L
T= 455 K
P= the unknown
R= 0.082 atm dm^3K-1mol-1
P= nRT/V
P= 0.0485 moles × 0.082 atm dm^3K-1mol-1 × 455/4.55
P= 0.398 atm
