Which equation can be simplified to find the inverse of y = x2 – 7?
a: x=y ^ 2 – 1/7 b: 1/x = y^2 – 7 c: x = y^2 – 7 d: –x = y^2 – 7 Answer:- a: x=y ^ 2 – 1/7 The correct answer is ‘x=y^2 – 1/7.’ To find the inverse of a function, we swap the position of the variables and solve for the…

What minimum mass of h2so4 would you need?
Answer:- The balanced chemical equation for the reaction is: 2Al(s)+3H2SO4(aq)→Al2(SO4)3(aq)+3H2(g) The molar masses of aluminum and sulfuric acid are 26.98 g/mol and 98.079 g/mol respectively. The minimum mass of H2SO4 required to dissolve the aluminum block is calculated by: (15.4 g Al) / (2 mol Al/mol H2SO4) * 3 mol H2SO4/mol Al = 23.1 g H2SO4…

What mass of h2 gas would be produced by the complete reaction of the aluminum block?
Answer:- The calculation of the moles of aluminum (molar mass is 27 gram/mol): n = m/M = 14.9 / 27 = 0.551 mole of Al In accord with the reaction flanked by sulfuric acid and aluminum: From 2 moles of aluminum ==> we get 3 moles of Hydrogen gas With the aid of cross multiplication 0.551…

The international space station makes 15.65 revolutions per day in its orbit around the earth.
Answer:- The radius of orbit is given by the expresson R = ∛(μT^2)/(4π^2 ) Where μ=398.6 .〖10〗^3 〖km〗^3/ s^2 , is the geocentric gravitational constant and T =〖(15.65rdp)〗^(-1) =〖(1.81 .〖10〗^(-4))〗^(-1) is the period of revolution. Substituting values, obtain: R = ∛(398.6 .〖10〗^3 〖5521〗^2)/(4π^2 ) ≈6752 km Subtracting the Earth’s equatorial radius, 6378 kilometers, obtain the height…
