The two systems would be respiratory and circulatory i think not completely sure tho <span />
The speed of the car = 22.25 m/s
<h3>Further explanation</h3>
Given
A distance of 22.75 km
Time = 17.04 minutes
Required
The speed (in m/s)
Solution
Speed is the ratio of distance per time
Can be formulated :
v = d/t
v= speed, m/s
d=distance=m
t=time,s
Input the value :
In this question, XB3(aq) is an ionic compound which will have the releasing of 3 B⁻ ions ions in water for every molecule of XB3 that dissolves.
XB3(s) --> X+(aq) + 3 B⁻(aq)
[B⁻] = 0.22 mol XB3/1L × 3 mol B⁻ / 1 mol XB3 = 0.66 M
The answer to this question is [B⁻] = 0.66 M
According to the image, we can say that to form an ice cream unit you need 1 scoop of ice cream, 1 cone, and 1 cherry. In other words, the ratio between all the reactants is 1 to 1. Therefore, the limiting reactant will be the one with the least number of units.
If we count the amount of each of the reactants we have:
• 10 scoops of ice cream
,
• 7 cones
,
• 12 cherries
In less quantity are the cones, that is to say, that at most we can assemble 7 ice creams. Therefore, the limiting reactant will be the cone.
Answer: (B) Cone
