Answer:
As the amplitude of pendulum motion increases, the period lengthens, because the restoring force −mgsinθ increases more slowly than −mgθ (sinθ≅θ−θ3/3!for small angles).
Answer:1.309 x 10^24 oxygen atoms
Explanation:
Molar mass of N2O4,= 2 x Molar mass of Nitrogen + 4 x Molar mass of Oxygen
= 2 x 14.01 + 4 x 16.0
= 92.02 g/mol
One mole of a substance is equal to 6.022 × 10²³ unit/ atoms/ molecules
In N2O4, there are 4 moles of Oxygen
if 92.02 g contains = 4 x 6.022 x 10 ^23 molecules
50.0 g wll contain= (4 x 6.022 x 10 ^23 x 50)/ 92.02g
1.309 x 10^24 oxygen atoms
Answer:
reduce using fossil fuels
Explanation:
fossil fuels are increasing our carbon footprint and so are green house gasses but we can't have too little greenhouse gasses or too much greenhouse gasses
Answer:
Na₂O will also form a brittle ionic compound.
Explanation:
Sodium is located in the same group as Potassium: Alkali Metals. This is because both elements have similar chemical properties. In term of their electronegativity, both elements are very close. Na has an electronegativity of 0.93, while K has an electronegativity of 0.82. This makes both ideal elements to create ionic compounds with Oxygen.
It is the first option bc if it absorbed heat it it will pressurize and could explode.
