Concentration of H+ ions in HNO3 solution is 10⁻¹ which is equal to 0.1 M
![\bf \: pH \: = - log[{h}^{ + }]](https://tex.z-dn.net/?f=%20%5Cbf%20%20%5C%3A%20pH%20%5C%3A%20%20%3D%20%20-%20log%5B%7Bh%7D%5E%7B%20%2B%20%7D%5D)
putting the value we get
![\sf \dashrightarrow \: pH \: = - log \: [ \frac{1}{10}] \\ \\ \sf \dashrightarrow \: pH \: = - log \: {10}^{ - 1} \\ \\ \sf \dashrightarrow \: pH \: = 1](https://tex.z-dn.net/?f=%20%20%5Csf%20%5Cdashrightarrow%20%20%5C%3A%20pH%20%5C%3A%20%20%3D%20%20-%20log%20%5C%3A%20%5B%20%5Cfrac%7B1%7D%7B10%7D%5D%20%5C%5C%20%20%5C%5C%20%5Csf%20%5Cdashrightarrow%20%20%5C%3A%20pH%20%5C%3A%20%3D%20%20%20-%20log%20%5C%3A%20%7B10%7D%5E%7B%20-%201%7D%20%20%5C%5C%20%20%5C%5C%20%5Csf%20%5Cdashrightarrow%20%20%5C%3A%20pH%20%5C%3A%20%3D%201)
So, the required option is A) 1
Answer:
True!
Explanation:
A spectrum is simply a chart or a graph that shows the intensity of light being emitted over a range of energies. Have you ever seen a spectrum before? Probably. Nature makes beautiful ones we call rainbows. Sunlight sent through raindrops is spread out to display its various colors (the different colors are just the way our eyes perceive radiation with slightly different energies).
Hope i helped!
A or B depends on what you mean by lit or glowing but when you place a wooden split in the sample the gas must reignite but there can be some confusion between hydrogen and oxygen mainly because a splint can cause a slight popping sound while it reignites but hydrogen pops are more violent and can most time extinguish the splint.
Answer:
#2.
Explanation:
Look at the charges. Both are positive, therefore both are cations.
