An igneous rock because its radiometric clock is reset, and potassiumargon measurements can be used to tell the number of years that have passed since metamorphism. <span />
Speed is measured in miles per hour. You have miles, so convert minutes to hours.
90 minutes x 1 hour / 60 minutes = 1.5 hours
540 miles/ 1.5 hours = 360 miles / hour
Hope I helped, even though this isn't Chemistry :)

Answer:</h3>
2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat
<h3>
Explanation:</h3>
- Balancing chemical equations involves putting coefficients on reactants and products.
- This results in an equal number of atoms of each element on either side of the equation.
- Balancing chemical equations ensures that the law of conservation of mass is obeyed.
- According to the law of conservation of mass, the mass of the reactants should be equal to the mass of products which is done by balancing chemical equations.
- Putting the coefficients, 2, 3, 4, 4, 4 on the equation makes the equation balanced.
- Therefore, the balanced equation would be;
2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat
