Yes, one can still sweat in velvet. While velvet is a luxurious and soft fabric, it is not particularly breathable, so it can trap heat and moisture against the skin. This can lead to sweating, especially in warm or humid conditions. It's important to choose clothing made from breathable fabrics, such as cotton or linen, if you want to minimize sweating. **

The weight of 1 mole of 53% nitric acid can be calculated using the formula weight percent = (mass of solute/mass of solution) x 100. Given that the weight percent is 53%, we can calculate the mass of nitric acid in 1 mole of the solution. Since the molar mass of nitric acid (HNO3) is approximately 63 g/mol, the weight of 1 mole of 53% nitric acid would be approximately 33.39 grams (63 g/mol x 0.53). **

The numbers 1 and 3 in 1-bromohexane and 3-bromohexane refer to the position of the bromine atom on the hexane chain. In 1-bromohexane, the bromine atom is attached to the first carbon atom of the hexane chain, while in 3-bromohexane, the bromine atom is attached to the third carbon atom of the hexane chain. These numbers indicate the specific location of the bromine atom within the molecule, which is important for understanding the structure and properties of the compound. **

To run a 1 km race in under 3 minutes, one would need to have exceptional speed, endurance, and training. It would require a high level of fitness, including cardiovascular endurance and leg strength. Consistent practice, proper technique, and a well-designed training program focusing on speed work and interval training would be essential to achieve such a fast time. Additionally, maintaining a healthy diet, getting enough rest, and staying hydrated are also important factors in optimizing performance for a race of this intensity. **

Task 94 in math can vary depending on the specific curriculum or textbook being used. However, in general, task 94 could refer to a specific problem or exercise related to a particular math concept. It could involve solving equations, working with geometric shapes, understanding fractions, or any other math topic. The exact nature of task 94 would need to be determined based on the context in which it is being used. **

To remove wrinkles from velvet, you can try steaming the fabric using a handheld steamer or the steam setting on your iron. Be sure to keep the steamer or iron a few inches away from the velvet to avoid damaging the fabric. You can also hang the velvet item in a steamy bathroom or use a fabric steamer to gently release the wrinkles. Avoid using direct heat or pressing too hard on the velvet to prevent crushing the pile. **

To calculate the number of atoms that decay in 1 hour, we first need to convert the half-life of cobalt-60 to hours. Since there are 24 hours in a day and 365 days in a year, the half-life of cobalt-60 is approximately 458,640 hours. Then, we can use the decay constant formula to find the number of decays in 1 hour: N = N0 * e^(-λt), where N0 is the initial number of atoms, λ is the decay constant, and t is the time. Given that 1 microgram of cobalt-60 contains approximately 3.7 x 10^14 atoms, we can calculate the number of decays in 1 hour. After plugging in the values, we find that approximately 1.6 x 10^9 atoms of cobalt-60 decay in 1 hour. **

In basic arithmetic, 1 + 1 equals 2 because when you combine one unit with another unit, you end up with a total of two units. Similarly, 2 + 1 equals 3 because when you add two units to one more unit, the total number of units becomes three. These equations follow the fundamental principles of addition, where the sum represents the total quantity when two or more numbers are combined. **
