Answer: -2m/s2
Explanation:
Using the following equation ; acceleration = Change in velocity / time
i.e a = v - u / t
where 'a' = acceleration
v = final velocity
u = initial velocity
t = time
Therefore; from the graph we have acceleration to be, 0 - 6m/s / 3s = -2m/s2
Given teh equation adn the heat of reaction, reaction 2's heat of reaction can be obtained by simply multiplying teh heat of reaction of 1 by 3. The final answer is -6129 kJ.
The correct answer is D. The solute in this solution is the solid sodium nitrate (NaNO3) which is dissolved in the solvent, the water. Solute is the minor component in a solution whereas the solvent is the major component in the solution.
Answer:
Nitropruside
Explanation:
Shock is a serious medical condition where oxygen levels in the body are low, causing a low blood pressure which can lead to organ damage and sometimes death. Shock can be caused by low blood volume or inadequate pumping action of the heart.
Nitropruside is a very potent vasodilator. It acts on the arterial and venous smooth muscles, causing smooth muscle relaxation and leading to decreased cardiac preload and afterload. A reduction in afterload gives rise to an increased cardiac output and blood supply to the cells is increased. This in turn reduces the need for the heart to pump more blood (a compensatory response by the heart due to the low oxygen levels), thereby reducing the oxygen demand of the heart.
