Answer:
1.3M
Explanation:
Convert from grams to moles:
molar mass of HCl = 1.01g(molar mass of H) + 35.45g(molar mass of Cl) = 36.46g HCl
1.2g HCl (1mol HCl/36.46g HCl)
= .0329 mol HCl
Molarity = mol/L (important formula for concentration)
Plug your values in:
Molarity = .0329mol/.025L
1.317M - but you used two significant figures in the question, so:
1.3M
Answer : Option D) the electrons in some metals pair up to create a magnetic field.
Explanation : Most of the metals are magnetic in nature including some exceptions. When the unpaired electrons get aligned with the magnetic field they posses magnetism. Also there are some paired electrons in metals which align themselves according to the magnetic field and create magnetism in them.
Answer:Granite forms as magma cools far under the earth's surface. Because it hardens deep underground it cools very slowly. This allows crystals of the four minerals to grow large enough to be easily seen by the naked eye. Look at the photo of granite above, notice the different crystals in the rock
