Answer:
upper left
Explanation:
it is a trend on the periodic table. Ionization energy increases from left to right(->) I t also increases down to up
Answer:
The mass of in the container is 2.074 gram
Explanation:
Given:
Volume of lit
Equilibrium constant
The reaction in which is produced
⇄
Here equal moles of and is formed.
From the formula of equilibrium constant,
M
Above value shows,
So in 2 L no. moles of = moles.
So mass of 0.122 mole of is = g
Therefore, the mass of in the container is 2.074 gram
Answer:
Parenchyma is the most simple and specialized tissue which is concerned mainly with the vegetative activities of the plant. The cells are isodiametric with well-developed intercellular spaces, vacuolated cytoplasm and cellulosic cell wall.
Collenchyma is the tissue of the primary body. The cells of the tissue contain protoplasm and are living without intercellular spaces. The cell wall articulate at the corners and are made up of cellulose, hemicellulose, and pectin.
Sclerenchyma is the thick-walled cell tissue. In the beginning, the cell is living and have protoplasm, but due to deposition of impermeable secondary board lignin, they become dead thick and hard.
Answer:
pH = 5.7
Explanation:
pH = -log[H^+]
For HCl pH = -log[HCl] = - log [2.10 x 10⁻⁶ ] = 5.7
Explanation:
The most reactive metals are found on the left of the periodic table, in the blue column, known as the alkali metals. Their reactivity increases as we go down column (group) one. Reactive metals, when attached to less reactive metals, have the ability to prevent the less reactive metal from rusting.
