The coefficient tells you how many molecules of that substance there is.
Antifreeze is an additive in water-based liquid to lower down the freezing point of such liquid. It is used to make use of the colligative properties of solutions specifically freezing-point depression for cold climate and boiling-point elevation to allow higher coolant temperature.
Explanation:
The high energy radiation causes damage to the cancer cell’s genetic material by inducing double-stranded breaks in their DNA. This acts as a signal for the cells to begin the process of apoptosis – induced cell death. The cancer cells then are unable to reproduce and die.
However the radiation my reach neighboring healthy cells and also destroy their DNA. If these genes for apoptosis are also damaged in the process then the cells may begin dividing with damaged genetic material resulting in more cancer.
Answer:
Amount of HCL = 0.00318 L of 3.18 ml
Explanation:
Given:
HCL = 2.5 M
NaOH = 0.53 M
Amount of NaOH = 15 ml = 0.015 L
Find:
Amount of HCL
Computation:
HCL react with NaOH
HCl + NaOH ⇒ NaCl + H₂O
So,
Number of moles = Molarity × volume
Number of moles of NaOH = 0.53 × 0.015
Number of moles of NaOH = 0.00795 moles
So,
Number of moles of HCl needed = 0.00795 mol
es
So,
Volume = No. of moles / Molarity
Amount of HCL = 0.00795 / 2.5
Amount of HCL = 0.00318 L of 3.18 ml
2NO + O₂ = 2NO₂
V(O₂)=10.5 L
V(NO₂)=2V(O₂)
V(NO₂)=2*10.5=21.0 L
21.0 liters of NO2 are produced
