the answer is b. oxide anion
Answer:
Only two elements are liquid at standard conditions for temperature and pressure: mercury and bromine. Four more elements have melting points slightly above room temperature: francium, caesium, gallium and rubidium.
Explanation:
Answer:In a sample of BrF the strongest interparticle force is the dipole-dipole force.
While Kr is the dispersion force.
And H2SO4 is hydrogen bonding
Explanation:
Brf is polar with a known dipole moment of 1.4D,dipole - dipole force and dispersion force are both present,the dipole-dipole force is the strongest interparticle force action on Brf considering its high boiling points
The bond formed by Kr will be non polar due to greater atomic size and low electronegativity.The force of attraction between the non polar is the dispersion force which is the strongest.
H2SO4 has a great polarity with a very strong hydrogen bonding.
I think the answer is sunlight
YES, I WOULD FIND THOSE ORGANISMS.
<span>The Kingdom of Tonga is a Polynesian Archipelago in Oceania consisting of 176 islands. During a month long coral reef research mission in Tonga, the Foundation focused on islands in the Ha’aipi group, Vava’u and Niuatoputapu. Haʻapai, directly west of the Tonga trench in the central part of Tonga, is made up of 51 volcanic islands and includes Kao, the highest point in the kingdom (1,046 m). Vavaʻu has one large island and 40 smaller ones, and includes the second largest city, a large harbor. The north side of the main island is lined by 200 m high cliffs and extensive open network of fjord-like channels that stretch inland on the north side. Nearly 300 km north of Vavaʻu, close to the border of Samoa is Niuatoputapu, a sparsely inhabited (population 150) eroded remnant of a volcano surrounded by a large uplifted reef. This island was badly damaged by a tsunami following a submarine earthquake off Samoa in 2009.</span>
